What is a fact is that both the country and the state are far better off with each other than they would be if separate, truly a symbiotic relationship.
The only other fact is that it is absolutely impossible for any of us to know what all the benefits that they each get from the other are ultimately worth and who is getting or giving "more."
To state your "fact" absolutely ignores the reality of how a symbiotic relationship works. Both parties get more than they give, that is why it works!!!!
California and the remaining states would all suffer if somebody were stupid enough to try to cut off their nose to spite their face!!! Just like we would have been if Texas had tried to back a few years ago.
