Er. ..in my country (Nigeria) a lot of people survive in a few dollars a day. Some even have to get by with a dollar or less

If you have some to spare I don't mind earning it. I'm a freelance writer

Here minimum wage is at least 10 euro per hour. Which is about the same in dollars. But life is also expensive. You would need 1500 - 2000 per month to live comfortably. And that's not really much.

For who are you writing currently? I bet you could earn a good wage with freelance writing when you offer your services to European or American market.
