Once you are accepted, schools will typically have you fill out an incredibly comprehensive financial aid application that will dig into your finances. They aren't just going to look at your current income and extrapolate. They will, however, look at your parental income, how many siblings you have going to college, how much you made when you were working, how much you have in the bank etc etc. Thus, if you hypothetically worked in finance in NY (or another expensive city), they will get the full picture of how much you made, how much went to rent / living expenses, and how much you have saved up etc. The amount of financial aid and the threshold for demonstrated need can vary significantly between schools. My school has been fantastic with financial aid.
