I am not trying to shame anyone, and yes, I am involved in researching solutions for a project that aims to help people in poverty empower themselves through providing data processing services. I also accept lower wages to be able to work on projects that are beneficial socially and have rejected offers to work in industries like high frequency trading that were very lucrative. I have spent hundreds of hours volunteering in my life teaching reading, ged, and esl in low income and even volunteered to teach ged material in a jail. We can all help in many ways, but the main point is having good regulation and rules is beneficial to capitalism. The best solution would be proper regulation of mturk to make sure that all businesses are on a level playing ground, whether they use mturk or another solution that at the moment may be more expensive in order to ensure minimum wage. But until that regulation happens, or mturk ensures minimum wage, I won't use mturk for any project.
