Right. Since urban areas are (in practice) fuzzily-defined, the real economic question is not "What are the rents?" but "What is the best rent/commute/quality-of-life trade-off available?" The fact that a few neighborhoods are expensive isn't relevant, but the fact that
every accessible neighborhood is expensive is a problem.
Defining "reasonable rent" as 30% of after-tax income (which is about the point at which governments should limit rent levels, IMO) and noting that an entry-level job in New York pays about $3500/month after tax, reasonable rent would be $1050 for a starter apartment.
It's not impossible to find a decent apartment for under $1000/month in "the greater New York area", but it is impossible to do so with less than a 30-minute commute.
