Oh no no no... never confuse agile corruption with feckless stupidity.
There is great art and cunning in the corruption that drives business in DC.
California, on the other hand, is run by bush-leaguers with nary the brains of boiled turnips.
Mark my words on this point: if CA secedes, they will learn is
very short order the pain of no more federal money, and it may well prove their undoing, economically. I do not believe, given the current raft of nuts and twigs pansies in charge, that CA could survive without the countless billions of federal monies they receive. I strongly suspect that CA would implode economically within a decade. The only avenue of temporary escape I see offhand would lie in the temptingly idiotic option of "nationalizing" resources such as silicon valley and selling them off to the Chinese to kick that can down the road for maybe another decade. After that, there would be nothing left to sell, save the earth beneath their feet, and who knows... those people are so bottomlessly stupid and corrupt, it would surprise me no whit were they to do that as well.
This becomes all the more plausible when you consider that CA would likely have to accept between $4 trillion. and $5 trillion of the national debt as a precondition of secession. I cannot imagine the feds would allow them much, if any, military accoutrements, apart from MAYBE the extant bases. I am not even certain the feds would let go of those. Can anyone here imagine them giving up Edwards? Mather? I cannot. So there you have a new stand alone nation, horribly mismanaged, no armed forces of which to speak, businesses probably running for the borders not to be sucked into the black vortex, with $4-5T in debt, much of it owed to China. How does anyone think this stands to work out? Not well for them, I suspect. And when they make it clear they cannot pay, they either become a Chinese protectorate or, more likely, territory, or China sends its navy to show them whose is bigger.
Seriously - can anyone here imagine that Ronnie Barrett would remain in CA, only to have his company drummed out of business by one means or another at the hands of the apes running CA government? I think Silicon Valley would largely pack up and flee, knowing they would be taxed and regulated into penury. Do we think the aerospace companies would want to have to deal with the international hassles or lose their candidacy for contracts with DoD? Perhaps, but again I don't see it as very likely.
There are so many entanglements and subtleties in the relationships between CA and the other 49 that secession would not be any simple matter. It would likely take years to consummate. I doubt the other 49 would approve in any event. How would they possibly benefit from it? I can see how they might lose.
