When I was younger, I also thought that way. I also felt that being artist has nothing to with money: a true artist will always create out of their internal need, not for money.

Then came the brutal reality: creating high-quality artwork needs time. Some can be created after work, but not that much. Some forms of art require expensive instruments. Some, like filmmaking, require collaboration and coordination of many people. So yes, I could do some forms of art part-time using the money from my day job, but I knew it was a far cry from what I could do when working on it full time. It's not capitalism, it's just reality.
