I wonder how much the cost of having the millionaires (in terms of the average resident paying for food, rent, parking, etc) is offset by their large contribution
I know not everyone would agree with me - but I think local governments almost always agree that attracting high earners is good for the city. Not only do they make schools and local government better funded but the raising of prices usually means higher wages (and more possible jobs) for the working class. There is a reason once Detroit lost its high wage workers the city sorta collapsed onto itself.
"1 percent of New York City residents generated 43 percent of city income taxes"
While I am not saying the current rate is fair or perfect, to say that the city wouldn't be hurt by losing tax revenue ignores the fact.
