California would be nothing without the supposed flyover states. They need them for food, power, water and a myriad of other things. Sure, California can obtain their own food, water, and power system, but that would require going hard on all illegals and leeches and using that money to create better infrastructure, which definitely needs fixing. Additionally, they’d need to bring back industries like coal mining and logging to sustain themselves. Essentially, they’d need to have someone like Trump in power to create a self-sustaining state, but that won’t happen anytime soon. Texas is more likely to survive a secession considering they have key industries still alive there is the help them. The same can’t be said for California. If Silicon Valley were to lose its prominence, their revenue would drop sharply and they’d possibly need to consider bringing back more agricultural jobs to survive.
