He didn't sell his works for very much profit because he was ignorant.
How much money did he make?
He only made $5 and couldn't sell it for a profit, so he was ignorant.
People sometimes have different things that they value in life. Maybe money is not that important to him. People will think it is rude that you are judging him that way.
Why are you so judgmental about such a simple thing, who cares about what he values in life, it was his choice and I can do whatever I want to. Don't get in my way.
Your entitled to your opinion. And I'm entitled to mine.
