True, but I think this is what the 1 laptop per child concept is all about. US minimum wage is 6.25/hour in other economies over a billion people would be happy with 1-2% of that. The trick is finding something useful for them to do and handing them the tools to do so. Anyway, I expect the cost of outsourcing low end jobs is only going to go down as digital work becomes more common.
PS: My point is mostly about what constitutes a "living wage" in most of the world and has little to do with Amazon Mechanical Turk as it exists right now. I expect most people using Turk are making a lot more than 1cent / min of work or are just doing it as a hobby where the cash value is almost zero incentive.
That person will probably not know how to use a computer, read or understand English.
