Not all my effort turned into dinners tho. And some types of work once paid for dinners but can't any more.
My #4 son is an artist/content creator. He eats based on what his non-art employment will buy. Perhaps one day people will find his art desirable and he could eat from that. It'll be a case where he worked long and hard on a project, was paid once for it and that's it for that.
That's what reality looks like for all artists - excepting a small percentage.
All that said, I really wouldn't want his dinner to come at the expense of everyone else being restrained by massive system of corrupt, draconian law that rigidly controls everyone's behavior for 150 years, primarily benefits wealthy and powerful rent-seeking corporations, is readily applied to censorship and is more likely to knee-cap other artists than to provide them anything like a living wage.
That seems indistinguishable from evil.
Once they hit the tipping point of broad cultural absorbtion (think Banksy) AND/OR raking in absurd amounts of cash, move their IP into the public domain more aggressively (think Disney, NYT, etc.). How exactly this would work should be debated.
They'd still own the IP and have all the rights to use it commercially, but other's would be able to use it as inspiration, remix and maybe even resell it if attributed (or cheaply licensed).
In other words: "IP-Tax" the unproportionally successful.
