I'm not a tax expert
(I was going to say I'm not a taxologist, but unfortunately that word actually exist
), but don't USA citizens(also know as Statians) have to pay taxes?
Yes, the federal tax % they pay is lower than in other countries, but they also have to pay state taxes which, even though they are lower, raise the total to roughly the same as the ones in countries with free healthcare.
I think in some states the taxes were higher than in the UK, which has absurdly high taxes close to 50% or something for high income earners(125k+).
But the most important thing is that you don't need a gofundme each time you get a cough
