The top 1% of earners pay 40% of New York City's income tax. The real question is how will NYC cope with the decreased tax base.
For instance, in CA, only about $100M a year out of the $100 billion a year budget is spent on transportation [1].
Because of prop 98 in CA, a minimum of 40% of the budget has to go to education [2].
In NY, it's only 4% spent on transportation [3].

If NYC is less expensive to manage per capita, I'm guessing that's reflected in a lower taxation rate. Don't they have a lot of room to raise taxes?
