Why are there casinos in low socio-economic neighborhoods in Los Angeles?

Focus on history of these neighborhoods. -maybe consider anti-poverty action or lack there of in LA county – laws surrounding legitimacy of these casinos – considering gambling is illegal in CA. – are these casinos exploiting the poor? – has this issue ever been discussed before? it would also be nice if you could find statistics on these neighborhoods, perform the simplest statistical tests and interpret them. if chosen as a writer I’d like a url or pdf of all sources used. mainly political science focused, please.
