MTurk employs a lot of people in developed countries. I have read they are starting to reject Indian based workers because of poor work quality. I can find employment for people who can provide a similarly high standard of work relative to workers in more developed countries, but who need the income more. Member participants would otherwise have had difficulties joining, say, MTurk because of a lack of computers, internet access, proper guidance, training... I don't think there are any companies helping freelancers find work because it's not very profitable, and yet there is a great need to reach people who are not working to their potential.
