Not a chance, NY is way too big, it would be all they ever did. Certain areas possible, but the whole city? Case in point the Dominicans, have had Washington heights for forever, how would one go about taxing them?
Mexicans? Colombians? Albanians and Russians and African Americans?
Without the political leverage, and police on the take, there is no way to enforce it, not to mention the blood that has to flow, they don't need the violence and attention that would bring, the money wouldn't even be worth it I don't think....
