The Tax Foundation used to compile these reports. Many high-income earners live in blue states, yet blue staters keep voting to send more money to Washington, so then Washington can redistribute it around the country. I never understood these voters.
So... how would a national divorce work?
If it were up to me, the red states would adopt a new constitution that would codify no law can be enacted to reduce or restrict the amount of CO2 emitted for any reason. Carbon emission taxes are not allowed. CO2 is not a pollutant.
That alone would increase the GDP 20-10%.
