Dude, it's literally how capitalism is built. Where do you think we get our cheap oil, chocolates, clothes, iphones, rare earth minerals etc from? The wealth of the west is built upon the suffering of the third world. And as I said in my previous comment, it doesn't look like things will change anytime soon.
You're doing the same thing again, conflating the way things are, with the way things have to be. I don't think it should be this way, I'm just acknowledging how the world currently looks.
People who fall into right wing views are the ones who believe the world should be unfair and you should push other people down. I think the world can and should be better but closing your eyes and pretending the horrors of capitalism doesn't exist is just stupid and wont help you build a better world.
Should a business that relies on poverty wages stay open? It seems to me that if you can't afford to pay your employees a living wage then you shouldn't be in business since your business is clearly not viable. It's like all these food delivery apps that popped up the last few years. They rely on venture capital and underpaying their "employees" to bring the price down. But eventually they'll be asked to make a profit and the prices will go up. I don't think people will keep on ordering in the same quantities when the delivery fees doubles or tripples, the bussinesses are just unsustainable and if you believe in market economies then they should be allowed to fail.
