I'm not privvy to where that decision is at this point in time but I can tell you that nothing can be traded. The normalization of slavery in the modern world is happening, and we consumers are enabling it. The Chinese government has shipped Uighur prisoners to factories across China. Modern-day slavery is woven into cotton T-shirts, pillowcases and sneaker laces. How much are millions of Uighur lives worth?
Slavery is a centuries old problem, and maybe some of it can be traded.
