1. Sounds good. I bet that lowers the amount of drug-related gang violence like nothing else would.

2. Same as in USA. I fund a lot of housing I cannot use via my taxes.

2 is not at all like the USA. USA has an ostensible progressive taxation for public housing -- the people on section 8 / public housing are poorer population than even the legal immigrants that can't get it.

Singapore's is regressive; they tax their massive % of population of ineligible immigrants so the citizens can have it essentially without means testing. It functions largely as a transfer of wealth from less rich to more rich.
