The difference in tax burden is give here: https://data.oecd.org/tax/tax-revenue.htm . It varies quite a bit by country, but the contrast with France/Nordics is particularly large
I’m not sure how income tax % to GDP is relevant here, but perhaps I am looking at a wrong thing, it’s quite painful on mobile
UPD: looked at the tax wedge, the US vs UK looks pretty similar to me- which supports my point.
Germany looks a lot higher, but they have 100% free tuition and I am not familiar with the rest of the benefits germans get.
