This is a poorly supported take, once you factor in the productive parts of the economy.
If you have a lot of farmland in a red state and the profits are reported in a blue state, then counting the reported profits on the corporate balance sheet will give a distorted picture of what is happening.
Look at e.g. General Mills, based in a blue state, but a great deal of what they buy are ag inputs from red states.
That is a good point.
But wouldn't the farm, selling to the big corp, realize the profits in their own state? Or are you saying the farms are owned by General Mills?
I was under the impression that most of the farms are owned separately and sell to General Mills.
