When they're starting out in the real world...those things are not going to be readily available on a starting salary.
But you're absolutely right: one can parlay a non-technical degree into a technical or scientific industry. But these "artsy" types who have no desire to venture outside their "creative" side, create artificial boundaries for themselves. Thus, they limit their opportunities.
I never admit what my actual degree is in unless I am asked point blank. And I just got my first smartphone so I can attach a card reader to it to accept on the spot payment. I admit, I am now in love with it. Every time an online payment is made it emits a cash register ring. So motivational!
As for “artsy” types that don’t want to venture outside their “creative” side... that sounds like a polite way of saying they want to be paid to play instead of work.
Many “creatives” aren’t as creative as they think they are because they can’t figure out how to effectively monetize their creativity, which is actually where most of the hard work is required.
Sometimes they aren’t actually very skilled or productive at what they want to do, or they are wholly derivative and not original in what they create. Copycats forever following the trend wave instead of riding it.
