Do you have some links that show the tax burden for Europe vs US is similar for low 6-figure earners? I can find plenty of calculators that estimate total tax burden for the US states, but not most European countries.
For example, I used someone in New Jersey (a US state known to be high-tax) vs France at a salary of 100K (which is the same in Euros now!): In NJ, including Federal, state and sales taxes, total tax is $27K. That seems to be a far cry from the $41K (sorry, Euro) I get in France from a very basic calculator that only includes country-level taxes AFAICT.
