i don't know enough to comment on the cost of "normal" living, but think about what happens in NYC the moment you get laid off or, even worse, get sick. I think at that point Paris starts becoming a lot more attractive if you're working class..
>Comparing between countries with massively different demographics is pointless. The US simply has far more criminality than other wealthy nations.
Yes, that is exactly related to the point OP was trying to make? Where does this crime come from? Maybe instead of useless, if not counter-productive mass incarceration, we should focus on rehabilitation and more importantly improving social injustices that are the causes of the higher crime rate sin the US.
