NYC, by virtue of being relatively compact and with high population density, of course requires fewer dollars per capita to provide the same services as a spread-out suburban enclave. But it doesn't take in less money than that suburb. It takes in significantly more.
They tax property at a higher rate. If you rent, your rent includes the taxes. You pay either way, the specific tax structure doesn't make a huge impact. If the city provides services, you're paying for them.
I wish people like you would quit apologizing for mismanaged governments that steal and waste so much money. There are clear examples of prosperous states where they don’t tax at all and they have thriving middle classes, good jobs for all that want them, and just as much infra as a high tax state.
It’s like denying “the science” when we have clear empirical evidence the people of a state can thrive without high taxes and that lots of people will not thrive in a high tax state. It’s clear, don’t you see it? Why do you deny what is in front of you and obvious?
I’m not sure there’s a specific number. For me personally, it would feel fairer if the city and state weren’t flagrantly, openly, unapologetically inefficient and wasteful.
