Why do people assume that every homeless person is both an idiot and an addict? Especially in cities in which real estate is as expensive as Los Angeles, the overwhelming majority of homeless people aren't there because of addiction issues. All the numbers I have seen suggest that only a quarter of LA's homeless population has addiction issues and even still the causal relationship isn't clear. When you live on the streets, the momentary escape of drugs is pretty alluring, but probably not as alluring as getting off the streets.
