Wow... hysterics much? By your "logic", we are all "slaves" by paying taxes for programs that we don't personally benefit from. Not that we are paying for the benefits we get now, we are borrowing from future generations...
Obviously, if we have such a program, it will come from higher taxes on the wealthy, which is always a good idea, and they probably CAN be said to have benefited from the economic exploitation of black people over the last 400 years.
Well, the parameters you laid out in the OP were a bit silly. That doctor making $400,000 is paying FAR more in taxes than that Mechanic making $40K.
Here, let me help you out.
Just going by the Single Filing- The black doctor pays 24% of his income on $400,000 - or $96,000
The white mechanic (who must really suck at his job, because average pay for Mechanics is 37-70K according to Glassdoor) is paying 12% - or $4,800
So that black doctor is paying 20 times what the Mechanic is paying... he'd probably be paying himself. Or conversely, he is paying for programs that probably benefit that Mechanic more then he is getting.
No, actually, it wouldn't. We've already done this, when we paid reparations to Japanese-Americans who were incarcerated during WWII. Each Japanese-American who was locked up in a camp received $20,000. It didn't matter if they were one of the people who was only held for a year, or the ones who were locked up for the duration of the war. It didn't matter if they were at one of the nicer camps or one of the awful ones. it didn't matter if they were economically devastated or did okay for themselves. Every last one of them got $20,000. Actor George Takai donated his to charity. $20,000 in 1988 was not a life-changing amount no matter what tax bracket you were in. It was the acknowledgement that the government did wrong that was important.
So let's say we give every African American a payment of $20,000 and a formal apology for slavery and everything else. Seems reasonable. It's not the amount of money that really is the issue, it's the acknowledgement that the country did these people wrong.
