Rent, Utilities, Groceries, etc. All of which are exorbitant in NYC. I read a study a few years back, that to live comfortably in NYC - and by comfortably they meant a studio apartment, groceries and one night out per week - you would need an annual salary, before taxes, of $120K. It is not realistic to have an AHL team in NYC and what is more, there is no need.
I also don't think you really understand the difference between the way the United States operates and the way Sweden (or other European countries) do. We don't have social safety nets. Basic necessities like cell phone bills are insanely overprice. And on and on......
It is significantly easier to survive in most, if not all, European countries when compared to the USA. And New York is one of the more difficult cities in all of the US.
