Artists are not the only ones who make a stink about this; it's inherent to the capitalist mode of production. Everyone involved in a venture is risking something, but the law only rewards specific kinds of risk with equity ownership over the venture. Other kinds of risk are solely rewarded with monetary wages at sub-profit margins. That's why labor unions exist, and why the nation's elites work tirelessly to stop them.
But with artists, there's a particular extra wrinkle, in that the law created a middle tier of reward specifically for the efforts of creative workers. Copyright was specifically intended to allow authors to have their own business ventures without necessarily having to share in the same risks that equity owners do. So, naturally, those equity owners all colluded with one another to steal this other form of equity and wear it as a second shell.

I would argue that it's not solely the law rewarding that kind of risk, it's the market. There is no law that says that only equity owners can enjoy massive profits. Some employees get paid 7 figures, 8 figures, or more, even without equity.
Generally speaking, the rewards go to the hardest parts, the riskiest parts, the parts with the least supply and the most demand.
You are taking far more risk by being a business creator and blazing a new trail, than you are by studying a fixed set of knowledge and techniques to train to become a Front End Software Engineer or some other kind of well-defined high-demand pre-defined role. And the evidence for this is the fact that there are millions of people who've shaped themselves into that safer mould, and very few who have done the former.
And this doesn't just apply to owners vs employees, it applies within each group, too. There are far more restauranteurs than search engine founders, as the former is simply a less risk and less competitive endeavor. (Competing with your local market vs competing with the world.) And artists who create unique works tend to earn a lot more than copycats. Artists who master rare skills tend to earn a lot more than people generating stuff off Midjourney. Etc. Risk tends to go hand-in-hand with reward.
Of course there are exceptions, e.g. rent-seeking, sabotage, monopoly, collusion, etc. that can earn you a lot without you providing a lot of value or taking a lot of risk. And a huge role of the law is to make as much of this illegal as possible, to force people into more value-creating activities by process of elimination.
