Yes, the conditons vary, but that it's not that the western nations are better or anything. The harsh conditions do exist.
For instance, think about chinese-run textile factories or restaurants in Chinatown in NYC. The same. Or I give you an example about the Japanese factories in Japan hiring many many Chinese workers way below the minimum wage for the labor for long damn hours, which is rather institutional and is a serious human rights violation. There have been suicides, homicides, and protests there as well because they are shit-holes.
So, I'm saying, these places are everywhere, the colonial type of exploitation exists, but many of us do not know or don't even care what these places really are inside and so on.
