How can taxes build a better society?

As we await Rachel Reeve's budget announcement, Laurence Fletcher wonders what positive tweaks can be made to our economic system.

Laurence Fletcher is a journalist at the Financial Times.

Few doubt that Chancellor, Rachel Reeves, will be putting up taxes when she presents her first Budget on October 30. The political narrative of recent months has very much been of an alleged fiscal “black hole” of £22bn - or is it £40bn? - that somehow needs to be filled.

While the size of the shortfall and the identity of those responsible are both hotly disputed, and despite a lack of detail from the Treasury about what it actually consists of, the questions now being asked are not whether taxes will rise but which ones and by how much.

Months of speculation have focused on employer National Insurance, capital gains tax and freezing income tax thresholds as areas that Reeves could look to for the additional revenue. But beyond the immediate issue of raising enough revenue to make good any shortfall, lies a deeper, trickier question about the way in which taxes should be levied for the good of society. If a government is to force people and companies to hand over their money, then what is the most ethical way to do this? Who should pay and who shouldn’t? How can tax be used to reduce inequality and build a better society?

Answering such questions is, of course, far from straightforward, because there are plenty of other factors in play.

For instance, some taxes are surely levied because they are simpler to collect. Take income tax - an unpopular measure introduced in 1799, then abolished before being reintroduced as a supposed temporary measure. It could certainly be argued that taxing people’s income - their attempt to get on in life and improve their lot in life - is less “fair” than taxing wealth that has been accumulated by someone’s ancestors years ago. Working hard and earning income is often surely a way of breaking down class divisions. But income tax - contributing 28 per cent of UK government tax take in 2023-24, according to The Institute for Fiscal Studies - has the advantage that it is relatively difficult for the average worker at a UK company to avoid it. Ease of levying it is surely a driver.

Equally, some taxes that might seem “fairer” have deliberately not been levied because of the difficulty in collecting them, and/or because to try to do so could be counterproductive. A wealth tax, for instance, would be “economically damaging”, according to one of the UK’s highest profile tax experts, Dan Neidle. Or take the politically contentious issue of non-doms, a colonial era tax break allowing rich foreigners to avoid UK tax on overseas income. It would be fairer, the argument goes, to tax them on the whole of their income. If they are going to be resident in the UK, then surely they should be taxed like a UK resident whose home is here?

Former Chancellor Jeremy Hunt abolished this regime earlier this year but left a number of concessions that the incoming Labour government pledged to abolish. But non-doms are tax-sensitive and highly mobile, and a number of jurisdictions compete to attract them. Many are entrepreneurs and wealth creators that many countries need. Reports have suggested a clampdown could raise no money or even cost money and could drive people away.

So what can be done to use tax in an ethical way? Paul Williams, research professor of marketplace theology and leadership at Regent College, Vancouver and chief executive of the Bible Society, takes a perspective that he believes offers some solutions.

He takes as his starting point a story in the gospels, where Jesus is asked whether people should pay taxes to Caesar. The question is a trap - either Jesus gives his backing to taxation that is highly unpopular with the Jewish people, or he rejects the tax in an act of rebellion against the Romans.

Jesus replies that they should “pay to the Emperor what belongs to the Emperor, and pay to God what belongs to God.” We are to pay our taxes to those in authority, but we are also to honour God.

While Williams believes that too much emphasis is placed on the Budget and political parties’ promises to be able to fix everything, and that a more radical rethink of our economy is required, he also sees room for positive tweaks to the current system.

One key area is the property market, the manifestation of so much inequality in society, with some people owning multiple houses while others cannot afford to buy one. Williams argues that the ready availability of debt finance has allowed those who already hold assets to easily acquire properties, turning real estate into an investable asset class to the detriment of many of the poorer in society.

“The reason there’s so many homeless people and empty houses is due to debt finance. It makes it easy for a relatively small proportion of the population to acquire a large percentage of the assets.

“The system has allowed a structure in which a small advantage in the beginning can lead to big, big differences over time.”

Williams highlights parts of Devon and Cornwall that have been “completely ruined” by wealthy people from elsewhere buying second homes that used to belong to locals, leaving property out of reach of anyone who lives and works there.

Nevertheless, he believes taxation can be used in this area to help level the playing field.

He proposes a “pretty punitive” marginal rate of tax on ownership of more than one home. (Stamp duty only partly does the job and is a blunt instrument also affecting people moving homes, thereby makes mobility expensive).

“You want to disincentivise the way the housing market is used for speculation,” he says.

“Housing is being treated as a commodity. The problem is, it’s not; it’s not just an asset. It has utility value and a communal and quasi-spiritual value, enabling people to feel rooted.”

Buy-to-lets, meanwhile, are better than having empty second or third homes, but “wouldn’t it be better if occupiers could buy that house?” he adds.

Meanwhile, research by the Financial Times recently found a huge wealth gap between the average millennial and the top 10 per cent of millennials, who are benefiting from family wealth to accumulate substantial housing assets.

So would increasing the rate of inheritance tax - one of the most hated of taxes - and/or lowering the threshold also help reduce some of this inequality? After all, how is it fair that one child in the UK is born to inherit large property wealth while another is born to inherit little or nothing? Or, even worse, that second child will only ever be able to afford to be the tenant of the first, paying them rent for the rest of their lives? Williams is not a fan of inheritance tax per se, arguing that it is “not part of the package” in a Biblical image of a flourishing economy. But he adds an important caveat: “the playing field is not level".

“There might be circumstances to impose a one-off tax on the very wealthy… if you want a transition to a more equitable society.”

Such steps are not easy to take. It is, he admits, probably “career suicide” for a politician to adopt such views. But if we are to take steps towards a fairer way of life, and avoid a two-tier society in decades to come, then maybe the conversation needs to shift this way. Perhaps the Budget could be the time to start.

When someone makes a claim, ask yourself these questions

How stories, statistics, and studies exploit our biases.

“Check the facts.”

“Examine the evidence.”

“Correlation is not causation.”

We’ve heard these phrases enough times that they should be in our DNA. If true, misinformation would never get out of the starting block. But countless examples abound of misinformation spreading like wildfire.

This is because our internal, often subconscious, biases cause us to accept incorrect statements at face value. Nobel Laureate Daniel Kahneman refers to our rational, slow thought process – which has mastered the above three phrases – as System 2, and our impulsive, fast thought process – distorted by our biases – as System 1. In the cold light of day, we know that we shouldn’t take claims at face value, but when our System 1 is in overdrive, the red mist of anger clouds our vision.

Confirmation bias

One culprit is confirmation bias – the temptation to accept evidence uncritically if it confirms what we’d like to be true, and to reject a claim out of hand if it clashes with our worldview. Importantly, these biases can be subtle; they’re not limited to topics such as immigration or gun control where emotions run high. It’s widely claimed that breastfeeding increases child IQ, even though correlation is not causation because parental factors drive both. But, because many of us would trust natural breastmilk over the artificial formula of a giant corporation, we lap this claim up.

Confirmation bias is hard to shake. In a study, three neuroscientists took students with liberal political views and hooked them up to a functional magnetic resonance imaging scanner. The researchers read out statements the participants previously said they agreed with, then gave contradictory evidence and measured the students’ brain activity. There was no effect when non-political claims were challenged, but countering political positions triggered their amygdala. That’s the same part of the brain that’s activated when a tiger attacks you, inducing a ‘fight-or-flight’ response. The amygdala drives our System 1, and drowns out the prefrontal cortex which operates our System 2.

Confirmation bias looms large for issues where we have a pre-existing opinion. But for many topics, we have no prior view. If there’s nothing to confirm, there’s no confirmation bias, so we’d hope we can approach these issues with a clear head.

Black-and-white thinking

Unfortunately, another bias can kick in: black-and-white thinking. This bias means that we view the world in binary terms. Something is either always good or always bad, with no shades of grey.

To pen a bestseller, Atkins didn’t need to be right. He just needed to be extreme.

The bestselling weight-loss book in history, Dr Atkins’ New Diet Revolution, benefited from this bias. Before Atkins, people may not have had strong views on whether carbs were good or bad. But as long as they think it has to be one or the other, with no middle ground, they’ll latch onto a one-way recommendation. That’s what the Atkins diet did. It had one rule: Avoid all carbs. Not just refined sugar, not just simple carbs, but all carbs. You can decide whether to eat something by looking at the “Carbohydrate” line on the nutrition label, without worrying whether the carbs are complex or simple, natural or processed. This simple rule played into black-and-white thinking and made it easy to follow.

To pen a bestseller, Atkins didn’t need to be right. He just needed to be extreme.

Overcoming Our biases

So, what do we do about it? The first step is to recognize our own biases. If a statement sparks our emotions and we’re raring to share or trash it, or if it’s extreme and gives a one-size-fit-all prescription, we need to proceed with caution.

The second step is to ask questions, particularly if it’s a claim we’re eager to accept. One is to “consider the opposite”. If a study had reached the opposite conclusion, what holes would you poke in it? Then, ask yourself whether these concerns still apply even though it gives you the results you want.

Take the plethora of studies claiming that sustainability improves company performance. What if a paper had found that sustainability worsens performance? Sustainability supporters would throw up a host of objections. First, how did the researchers actually measure sustainability? Was it a company’s sustainability claims rather than its actual delivery? Second, how large a sample did they analyse? If it was a handful of firms over just one year, the underperformance could be due to randomness; there’s not enough data to draw strong conclusions. Third, is it causation or just correlation? Perhaps high sustainability doesn’t cause low performance, but something else, such as heavy regulation, drives both. Now that you’ve opened your eyes to potential problems, ask yourselves if they plague the study you’re eager to trumpet.

A second question is to “consider the authors”. Think about who wrote the study and what their incentives are to make the claim that they did. Many reports are produced by organizations whose goal is advocacy rather than scientific inquiry. Ask “would the authors have published the paper if it had found the opposite result?” — if not, they may have cherry-picked their data or methodology.

In addition to bias, another key attribute is the authors’ expertise in conducting scientific research. Leading CEOs and investors have substantial experience, and there’s nobody more qualified to write an account of the companies they’ve run or the investments they’ve made. However, some move beyond telling war stories to proclaiming a universal set of rules for success – but without scientific research we don’t know whether these principles work in general. A simple question is “If the same study was written by the same authors, with the same credentials, but found the opposite results, would you still believe it?”

Today, anyone can make a claim, start a conspiracy theory or post a statistic. If people want it to be true it will go viral. But we have the tools to combat it. We know how to show discernment, ask questions and conduct due diligence if we don’t like a finding. The trick is to tame our biases and exercise the same scrutiny when we see something we’re raring to accept.
