@alisha-- I agree with you, but I don't think it's as difficult as it seems.
There was a lot of social dumping taking place in Europe. Many European companies had hired foreign workers from poorer Eastern European countries. But when some of the same countries entered the European Union, and fair labour laws were implemented, social dumping largely ended.
European companies had to increase their wages and give benefits to those workers. Some of them might have hired workers from Africa and elsewhere to keep costs low. But as more and more countries become wealthier and developed, I think this issue is going to take care of itself on it's own.
What do you think?
