Pandering is free.
I imagine infrastructure-based incentives will be popular in New York. Large tenants make big infrastructure possible. That enables further density, which means more jobs, more municipal budget and more demand for local commerce. Turning Amazon's HQ2 into the catalyst for building out Western Brooklyn and LIC infrastructure isn't a bad trade for the city. (Tax credits would be tone deaf, but if done in a budget-neutral manner could be okay.)
New York City is a commercial centre. Pragmatism wins votes.
