Slavery is bad. That's the sort of massively uncontroversial statement we can probably all get onboard with (if not, maybe it's time to re-examine your life, Mr. “I still live in the 18th Century”). No matter who is enslaving whom or what they're doing with all that concentrated human power, it's almost guaranteed to be a bad idea.
Yet that doesn't mean we've scrubbed away all the traces of this exceptionally bad idea from our modern world. Far from it. Go traveling around the Americas, Europe, Africa or the Caribbean and you'll find entire cities that were built on the groaning backs of enslaved peoples. Cities that today are sometimes some of the biggest tourist hotspots there are.
