Let's say revenue is 1cent an minute for 40 hours a week and 48 weeks a year. That's 9,216$ / year. Split the cost of a low cost energy efficient PC 300$, electricity ~100$, and internet 400$/year, over 1 year. And your left with ~8416$ which works out to ~700$ a month. In 2004 a southern China factory job would pay about $120 a month for long hours and often dangerous conditions. There are more than 4 billion people who gladly take that job but most of them don't have the skills to do so.
PS: If you think my numbers are a little off 8000$/year places someone in the top ~15% of the worlds income earners. (http://www.globalrichlist.com/)
That person will probably not know how to use a computer, read or understand English.
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.
It does appear to work though, so maybe that's not a valid concern for many people. I wonder how exhaustible a resource people like that are, though. If MT were to become more widely used, would it fall off a cliff as the supply of people doing it "just for the heck of it" dried up and they are forced to ask for market rates?
I'm reminded of the first time I ever went to a casino. After an hour of exploring and putting the occasional dollar in a slot machine, I was about five dollars down. "Oh well, I thought, five dollars for an hour's entertainment is pretty good value!". Then on the next machine, I won ten bucks, and found myself thinking "An hour's work for five dollars? What a gip!"
That said, your study does answer my question. People see it as easy money that they can pursuit while doing other things or when there is nothing else to do, which makes sense.
The problem you have is the lens you're looking through. No one paid you to post here, no one paid you to participate in a social network, watch a youtube video, let alone make a blog, yet a whole heck of alot of the folks on the planet do it.
People need to stop looking at turk through the "job" lens because it will never ever make sense. But if you look at it through the multitasking, social media, bored outa my gord, what the hell, yearning to participate in something, be apart of something, advisory and authority lens it makes much more sense.
Meanwhile, read up on turks, get to know their behaviors and find out the why behind their actions.

Don't take my word for it, go ask them yourself, make HIT, put it up there and see for yourself. But take the traditional "this is a job" lens off cause that is a classic misguided view of mechanical turk.
