Whether if you agree or not black Americans are owed reparations

For most of those, I'm in total agreement.
If there was a (say 80%) agreement with that in a national vote, what kind of reparations would work best?
If 13.4% of US citizens are of African descent, how does one distribute the compensation in a fair and egalitarian way?

Who exactly pays?
Do we expect new immigrants to pay, who have never committed a single sin against a Black American?
Is it all citizens irrespective of whether they have ever caused harm?
Is it only the descendants of slave owners and others who committed racist crimes, leaders who enacted racist laws and funded racist practices, teachers who taught racism...?
How much do they pay? How many payments over what period of time?

I am not trying to imply that compensation is wrong. I don't think it is.
But I think perhaps it might be better if it was not a direct financial payout.
Rather, I think the best way would be to put far more funding into much higher standards of free education, medicine, maintenance of public infrastructure, and better, stricter and fairer standards of justice.

In my will, I have left everything I own to the Gunditjmara people to compensate them for the crimes of my ancestors.
To be honest, there is no way to compensate for the murders, rapes, theft of land, children stolen and sent into slavery, or the destruction of languages, beliefs and cultures. The horrors of it are so great that no amount of money could compensate.
And the work of healing, though it has begun, will take many generations.

I wasn't aware of the CIA causing the crack epidemic.
I would believe it if I saw the evidence.
Crack is a problem in Australia too, but here it's almost exclusively a white addiction.
