Idk, I'd say a girl consigned to marriage against her will, deprived of education and autonomy and forced into sex acts is just as vile as chattel slavery. If anything the difference is semantic. The article is pretty open about the methodology being somewhat suspect, but it suggests that the number could be much higher. The users of this site seem to have a very black and white worldview, sometimes, and assume that just because an organization is captured by capital, such as the UN, it is wholly evil. I'm sure there are some very principled people working in the ILO, and probably some decent comrades, who've decided that working for the UN was the best way they could be a force for good in the world. It's wholly believable to me that the fallout from various ongoing conflicts, the destabilization of governments by US/NATO, COVID, and climate catastrophe have put families in the position to make the horrifying position to sell their underage daughters to men who can afford them. I don't doubt that parts of the world have returned to the bronze age. Modern society is built on the flimsiest of foundations, it doesn't take much to bring it crashing down.
