The issue is actual economic oppression in the present day — with historical antecedents — toward a particular class of human by the current, and historical, power class.
Ok. Let’s suppose you could gather more than a few measly percentage of the population to consider a tax increase to pay off this “actual” economic discrepancy.
How do you propose to measure that?
This is redress of a harm done to a class of humans over many generations up to and including the present day.
Ok, now you’re contradicting yourself. Above, you said this was about “present day”. Now, you’re wanting to compute an aggregate economic effect over time. That’s far more difficult, and far less fair.
it’s hard to imagine that it is going to be persuasive.
You think you’ve been persuasive? If I had to pick several ideas I’ve heard come out of the American left over the last decade or so that have absolutely no chance of being legislated, reparations would be at the top of the list. You might have a shot at a one time or short term payout of a few bucks, but even the democrats would blanche at the amount of borrowing or taxes that would be required for the payout to be substantial.
