There will be some wealthy New Yorkers who will leave NYC because their politics and world view is fundamentally aligned with that of our president. But that profile is not a good fit for most wealthy New Yorkers, just as it is not a good fit for New Yorkers in general.
In the coming war (and yes, it will be a war) between the forces of community and kindness, versus the forces of selfish acquisitiveness, most wealthy New Yorkers will choose the former. I know many wealthy New Yorkers, and I can tell you first hand that the great majority of them are not at all like our president.
Those New Yorkers will be willing to pay more in taxes because (1) They understand that it is actually fair to do so, and because (2) They believe in this city, and understand what a unique and rare privilege it is to live here. The right wing fantasy that having a lot of money makes you as morally low functioning, narcissistic and sociopathic as our president is just that — a fantasy.
More tomorrow.
