Do you agree with either of these statements?

Illegal migrants come here and are a burden on services and the taxpayer. OR The only way to reduce inequality is to tax billionaires and giant companies who avoid tax.

They may seem on opposite poles of the political spectrum, but both anti-migrant campaigners and anti-capitalists share an identical mindset. Both are demonstrating zero-sum thinking; the belief that if one group wins, another has to lose.

In itself, zero-sum thinking isn't moral or immoral, right or wrong. But Economists claim it leads to poor economic policy, and they say evidence shows it is possible to create win-win situations for everyone.

But many of the main parties at Westminster also use zero-sum thinking in their political rhetoric - from Reform and the Greens, to the Conservatives and Labour. Also, the first past the post electoral system is literally a zero-sum process. So is this kind of thinking baked-into UK politics?

So are there particular groups of people that are more prone to zero-sum beliefs? Where did this mindset come from? What economic conditions encourage zero-sum thinking, and how deeply are these beliefs held?
