I have a friend who is a janitor in a Junior High School. He received his masters degree in business from Ohio State. This is what he chose to do with his life and he is quite happy.
Then again, he has invested very wisely and lives in a half million dollar home and both his kids go to prvate school. He frequently publishes articles in business trades and he has published a couple of books.
The job is irrelevant.
Sometimes the dog did eat the homework, but that's not the way to bet.
