Yes, they do. you know what ? in my country, the gov pay ~100usd for a teacher/a worker with 1-2 year experiences. Lmao , and very hard to find a job with good income. So 50 Usd meaning something right?! and with 5-10usd daily by uploading 300usd monthly, they can survive and its pretty good . Thats why you can can see almost uploaders come from asian countries. Its not a job but at least you can survive at present.
