Where did I say that, exactly? I welcome the opening up of economic opportunities to these populations. I just think that they deserve the same protections and pay for doing those jobs that Westerners would receive if they were the ones doing them, rather than just being pawns in a global system of labor arbitrage.
It's a bit rich to get up on a moral high horse and then declare from that elevated position that the life of a Bangladeshi worker is worth less than that of an American one. Companies aren't setting up in these countries because they are benevolent actors looking to help them develop their economies. They're setting up there because they can exploit the workers there in ways that they can't get away with doing back home anymore.
Workers in developed economies had to endure a century of bloody struggle to claw those protections into place; I would rather we construct an economy that allows this new class of workers to get them for themselves without having to suffer through that.
The fact that you can sit there on your computer and say "oh, those poor foreigners would be so much better off if they just let me decide for them so I could keep them in a third-world subsistence farming economy" just indicates that you are from a culture that's forgotten what it takes to modernize and improve. You can't build an industrial base off nostalgic dreams of agrarianism.
