It was Grant, the Whiskey Ring and the Compromise of 1877.
In the 12 years after the Civil War - when my great great grandfather returned to Alabama (he ran away to Mexico in 1860 and made a lot of money as a mercenary of sorts for the French - paid in silver pieces) - our family prospered.
Were there idiots they had to deal with? Sure! And we continued to prosper as best as we could (owned a farm outright that started the wealth being built) - in spite of an oppressive regime.
Had the Republicans not painted themselves into a corner with their shenanigans over Whiskey revenue - they could have pushed forward in spite of the country's Reconstruction fatigue. But they caved.
Jackson did the best he could and was a man of his time. Though - I agree 40 Acres and a Mule would have helped. Or one acre and a blacksmith shop, or a half acre and a seamstress shop, etc etc. It would have changed the lives of millions of black Americans TODAY. For those whose ancestors could not beat the system and get one up on the oppressors - I raise a glass.
How different their lives would have been had the Republicans not thrown us under the bus in 1877.
