For an idea as to how expensive that was, they finally paid off the debt in 2015. Not a typo.
Expensive but cost less then the way we did it, with a war.
No. You get no reparations.
The British paid reparations to slave owners for their emancipated slaves.
American slave owners never received any reparations.
“the British government spent £20 million, a staggering 40% of its budget in 1833, to buy freedom for slaves. That’s equivalent to approximately £20bn today, making it one of the biggest ever government bailouts. The cost was so high, the vast loans the government took out to fund it were only just paid off in 2015.”
