Ripanrocks, you can't ask a question like that since it depends on what part of the world you are asking about.
When I started I made $20 an hour. 2 years later I was making $60 an hour freelance. It depends on your employer, your negotiating skills, your contract, and your professionalism.
Just like you can't assume that you won't get paid for teach ground school. I got paid. Others do not get paid. Careful about making assumptions.
