Or are you saying that the advertising networks themselves train their users to act like rich people because an ad network with rich people is more valuable to advertisers (although in this case, the networks aren't paying the poor people)?
Side note: I'm not convinced that the people operating the like farms are wealthy by western standards. Having at one point been involved in the business side of paid captcha solving, this type of business attracts a lot of entrepreneurs with little experience who just want to make a quick buck.
I completely agree -- click farming is a way for second-world people to make a living using third-world labor. In the short term, this benefits the surveillance companies at the expense of their clients. In the medium to long term, it probably costs their investors and helps inflate another tech bubble. Seriously shady folks (think Experian, but completely unregulated, at best) will buy the data when it bursts.
