70% of students and 30% of the workers are unpaid to make money online

Hello steemit friend how are you all I'm not good at Hive account@ornima. Because we work online, about 70% of the students and 30% are employers and others.
Sadly, we only do the job but we do not get the profit. So, working hard to take money can not take money. What is the reason? We want to know.

It is not my claim, the demand of the people of the world. Do not put the result of hard work, because of the cost of keeping the money? And the right side of the web side is closed.
