6. I don't think the two are really connected.

The term "starving artist" is pretty accurate. The old fine artists were supported by the church and rich people. Everyone knows that artists work several jobs just to get by, like actors. No one goes into the art field to get rich and famous. Hitler was no different.

He had a chip on his shoulder and it likely would have been the same whether or not he got into an art school and was able to support himself through his art or any other profession for that matter.

He was a crazy psychopath whether or not he made it as an artist. Tons of starving artists for hundreds of years didn't turn into mass murderers. He had a serious and separate mental illness. If he were a waiter, a train conductor, a plumber, etc he would still be a psycho. Everyone has some chip on their shoulder but they don't end up destroying cultures and societies due to it.
