In 2007 one of the best violinist's in the world stood in a DC subway, in plain clothes, playing a $3.5M violin.
He played 6 pieces. Out of 1,097 people that passed by. 7 people stopped for 1 minute to listen. He made $50 in tips, and half of it was from one person who recognized him.
It can be up to $300 to listen to him play at a concert.
Most people don't value things because they truly recognize brilliance, or beauty.
You value things you pay for, you pay for things you value. Its hard to get someone to stop and listen to a masterpiece if you don't make them pay to do it.
