Marginal tax rates mean literally nothing.

Nordic countries pay significantly more in taxes any way you look at it. You'd get laughed out of the room if you talked to someone like Donald Trump about paying a 40% marginal tax rate.

and most folks in that tax bracket are doing things, other than paying short-term gains or regular income tax, to reduce their burden significantly.

And then add on Healthcare, child-rearing, and education costs and guess what...

USA Citizens pay more overall. Just not through "taxes." per -say.
