Airbnb won't go there if they were not filled, and every city needs visitors as well as residents. So airbnbs aren't a problem. Speculation isn't a problem as long as they keep the units occupied. And vacancy rate is lower than average in NYC. So it sounds like a simple fact that demand outstrips supply. Only way to "fix" it is by making NYC a less attractive place to move into (increase local taxes, reduce spending thus stimulating crime, etc.), or make it harder to move (something along the lines of Soviet registration system). Both appear to be less than desirable, to say the least. Face it: there is no way people could move limitlessly into a desirable city and keep it affordable. Whole point of attraction is unafforability.
