California's government - federal electives, state and many local have been making decisions and putting in place policies that we are now seeing the consequences of.
The pandemic didn't create the problem - it poured gas on the fire. The elected officials of the last 30-40 years created the problem. The housing shortage is 100% a government created problem. The homeless "problem" is 100% a government created problem.
We don't have to solve these problems - we can continue on as we are which is likely because it is the path of least resistance (accountability is hard for people and governments). But let's be honest about why things are the way they are.
