Of course the data doesn’t back it up.. and a lot of those blue states get bonus income due to things related to red states.
IE NY financial gets boon from economic activities of all states.
West Coast gets boon from all the imports for ALL states through their ports.
The idea that blue states are wholesale subsidizing red states is nonsense.
The whole thing is non sense. You cannot apply static analysis on what is the most dynamic of all situations, the secession of many states.
