Fun, little known, fact: compensation was paid when slavery officially ended in the British empire -- to the slave owners. The records of these payments exist. Many went to families that continue to form part of the UK establishment (at least one of the Camerons - not sure if David or Samantha or both - have ancestors on this list).
I can't for the life of me see anything wrong with asking the present generations of these families to cough up for, say, a fund to mitigate educational disadvantages for Black kids now in the UK. Of course there are constructive ways to redistribute some of the ill-gotten gains of the era of slavery. They just won't be pursued because - see above - the same establishment is still in charge.
Don Lemon isn't very smart, alas. But his prissy interlocutor is wrong; the holding facilities for slaves on the West African coast were typically provided by the European buyers. If African kings' descendants ought to pay reparations, then so ought the descendants of the Europeans who profited.
At one point the average time of a slave's survival after arrival on a plantation in the Caribbean was seven years - and I'm not even sure that is the lowest number across the different islands. They were worked to death, and that was on their European owners, no matter what had led to their enslavement.
The thing that this thread shows the most clearly is that teaching on the history of the Transatlantic slave trade continues to be woefully inadequate. It wasn't just another slave trade. It dwarfs the others, and it dwarfs 'modern slavery'. Nobody is openly embarking 25,000 people a year for sale at market today, while arguing that it's OK because they don't have souls or some such.
It has been argued, convincingly, that Transatlantic slavery created the conditions for industrialization - it made the modern world. Europeans didn't get richer than the rest just by 'work ethic' or similar. Useful reading on this point:

I don't normally feel ashamed of being European - it's not like I can help it - but some of the posts on here make me embarrassed to be so.
