If you're independent selling paintings, sure. Designing packaging or something commercial? 4 hours of work a week for nearly 6 figures. I know a couple graphic designers and they don't do shit for what they're paid.
You should probably tell the other millions of artists busting out 60+ hour workweek in industry for half that price where these jobs are. That could solve this problem overnight.
In a cosmic sense, no. Most of us are slaving away at some job when we would rather be doing something else but are bound by the need to fund lodging.
But in a more practical sense yes. There's not much personal nor logistical progression to make pushing pencils. Meanwhile, art is a craft that you can dedicate your life to improving and educating others on. It can be a career instead of merely a job to do.
