Art is an excellent skill.  Low overhead and timeless demand.  Art might be more appreciated after the oil age.  IMO, probably classical Greece spent a far  higher % of GDP on art than any fossil fueled society.  My sister paid a guy outside a mall to do a portrait of her dog, lots of opportunities out there.    
Yes. Probably why it's so suppressed.

There's no real "journeyman" training in art in the US, it's the plaything of the rich and distrusted by most nose-to-the-grindstone Americans. I was destined to become an artist, but my family crashed from middle class to welfare-class and art was just not trusted.

But no one ever got tired of looking at their own ugly mug!

If you've been around a bit, even the most bone-headed person can see that the present work-til-you-drop way of life is a scam. Most Americans are dropping dead before they ever collect Social Security, it's the top quintile, maybe the top two, living to collect. And everything else in the slush fund goes for .... I dunno, black helicopters or something.

It's looking good, get an old volvo and a shop, and stop spending so damned much money to make a little money. Instead, spend next to no money to make a little money.

If I keep going the way I've been, I'm going to have a heart attack and I'll have to gear way down anyway.

Well, more than the U.S., that is for certain. I remember reading/learning that in Golden Age Athens, a rich citizen was expected to either finance a play or a warship. To a major extent, this explains the incredible output of drama from a tiny city state more or less in the middle of nowhere.

The value a society places on something is neither an economic or a technological decision - it is a human one.
