California is not like Greece- as in if you think California is bad, Greece is literally 100 times worse. I read a few economic policy blogs in my non-real estate nerd time. There are problems with California governance for sure, but from time to time they post articles about the myth of the California decimation. California still has a lot going for it. I couldn't find an example article from a quick search, but they are out there. If by "welfare consumers" you mean immigrants, they have been an engine for economic growth since our ancestors got here.
News outlets like to create that sense of drama. What? There's an opinion piece in WSJ that says taxes, regulation, and public transport are bad!? Surprise Surprise! I'd be more interested in an article that has some hard data about the demographic trends. Remember Bruce Norris from the conference? What does he say? He was awesome predicting the long term Cali trends!
I do agree that the state has it's problems, but even those problems will create opportunities for smart RE investors.
