Best way in the US would be to make freedmen eligible for homesteading.
We didn't have the liquidity to offer fiat money and we didn't have anywhere near the specie at Fort Knox to properly compensate the freedmen for unpaid labor.
I have the impression that the current line of thought was that, the US at that time being largely an immigrant country, the best way to 'repair' slavery would be to just give the freedmen the same rights as regular immigrants had and let them start 'fresh' alongside them. Seeing how well most of the immigrant families did, just after one generation, the idea was that freedmen would work their way up from the bottom of the ladder just as quickly, or even faster since they had some advantages such as already speaking the language and knowing that land.
The backside of this was off course that just like with immigrants, it quickly became perceived that the people that did not advance socially, did so because some character flaw of theirs. In the popular mind that mostly came down to drinking, whoring or oyerwise '
giving in to their basest instincts'... This idea worked particularly well in the 'gilded age' as a way to explaining away why even the most disgusting immigrant was still better off than most African-Americans: it wasn't the color of their skin. It was all because of their '
lack of self control'. No fault on our behalf.... Reparations? Our fathers fought and died to free them. That's reparation enough.
