Exactly, it really matters what you get in exchange for taxation. Many central and northern European nations offer true value in exchange for taxes, not an elite that has all their politicians in their pockets and that eats up vast amounts of the total economy in order mint a few billionaires while still taxing the average guy a total of 50% or more in exchange for a below middle class quality of life.
All depends what income we're talking about, top 10% earners or average earners. Then it depends which US states we're talking about, because of the great variables. California has local, state and federal taxes, in addition to a 10% sales tax. Finally, we have to determine what benefits we derive from those taxes. In the US we have a great shiny military and not much else, while in Europe you get proper infrastructures, free healthcare and education. If you were to cost that in, you may find that even crazy taxing Finland is not so bad after all.
