25 cents per hour is roughly 45 $ a month. (8 h/day, 22 working days/month) I guess someone who would work for that wage lives in a rough country. As we all know from the news and documentaries, those countries often have horrible working conditions, like 60 hours or more a week and physically hard work. Isn't a mTurk job better than that? Also don't forget the lower prices in such regions.

The thing is this: NGOs and friends are trying since decades to solve humanitarian problems. Unfortunately they suck incredibly at what they are doing. The countries stay poor, the working conditions stay bad, war and crime continue.

I strongly believe that economical prosperity automatically leads to better living and working conditions. Just look at the African countries the Chinese got their hands in.

BTW, don't forget that there is not only competition between the workers but also between those submitting jobs. I.e. many mTurk users => more competition on the income side. Even better: competition with same working standards. You don't even have that in the U.S.!
