That’s why I deliberately did not say income tax rates. They ream you in other ways. Canada’s taxes as percentage of GDP are 31.7%. US is 26%. And on top of that I was referring to Western Europe, where they are close to or above 50% GDP.
That's still 6%, not 20%. (It also pays for college tuition, childcare, and parental leave.) It's also a bit weird to do it as gdp percentage instead of individual percentage, which obscures the individual/business split.
