As a white person.
Justice can not be served for black people or other racial minorities if we pull up the wealth ladder and tax them as they get money. The system was racist and allowed white people to get ahead if you tax everyone equally who do you harm the poorer and newer wealthy people. If you don't take from a subset of the population you harm
We had a racist system that allowed wealth to go to white people. We eliminated the slave labor 164 years ago and tradition of viewing and treating other races as less than(in theory 61 years ago). But the white already wealthy people already own everything and have generational wealth. We have not had a thing that helped black people specifically. They were suppose to get 40 acres and a mule. A generation hasn't even passed of being able to discriminate against races.
If you pull up the ladder of wealth you are only hurting new wealth which would be proportionally more black people versus targeting old wealth which would proportionally be white people.
Lastly Mamdani said he was describing the neighborhood he was targeting with his changes to taxing. He wasn't going to put language into law that it had to be white people.
49 years between 2000-2050. 25 would be the mid point with 24 years previous and 24 years to go. 182nd day of the year is July 1st so July 2nd is the middle point/day of the year with leap years being midnight of July 2nd into July 3rd. So this checks out
