American taxes vary way more than in Europe. You walk a mile to a nearby town and suddenly it's a different tax. Not by much, it's like less than one percent, but still.
Kinda goes to show that it's not helping to display them like that.
If Brazil, a much poorer country in comparison, can do it then so does the US. I think that arguments in the contrary don't hold any water and are poor rationalizations ("US is special").
