We're so used to political debates where the Republicans say "less regulation will solve X", the Democrats say "more spending will solve X", the libertarians say "X is none of the government's business", and each suggests that things will go swimmingly under their preferred way of attacking the problem.
Some things, though, just suck.
Schizophrenia is one of those things. You can't cure it. You can't treat it very well. There's not much to be done.
Sometimes bad things happen to good people, and no amount of "training teachers" or "diagnosing diseases" or whatever will change that.
It's a tragedy.
