Firstly, Finnish climate is a lot different than Southern California with an average temperature of 65F. If the government or society never acted on the problem in Finland it would be a humanitarian crisis with people freezing to death. It is much easier to neglect the problem in SoCal because of the climate. Second, the state of California is so far in debt, it would put a further strain on its economics. There is simply no money to pay for "solving" the problem, and because people aren't dying in the streets en masse (like they would in Finland during the winter) nobody wants to pay for it. Third, even if we could solve the problem practically, it would be a recurrent problem. There is a problem of people expecting handouts and capitalizing on them. So throwing money at the problem will simply not fix it. I'll end with an anecdote from 20-ish years ago. We were having lunch at McDonald's, and a homeless guy walks by: "Hey buddy, you gonna eat all that?". "Uh, yeah," struggling to finish my mouthful as I'm trying to answer. "Maaan, it ain't even fun being homeless anymore!" and walks away. How do you fix that?
