I think one of the reasons so many creatives feel cheated is there's far too much creativity, so the marginal value of more is low. In that situation of overabundance, some other step in the value chain will deliver most of the value, and reap the reward. This feels like exploitation, but it's just the market telling creatives they need to be producing something else.

How does a market determine cultural value. What is the value of a priceless family heirloom? What is the value of human connections? How do you communicate these thoughts without first assuming that markets correctly assign value?

In this case, it’s postulated the biggest single factor is a monopsony.

The problem with collective bargaining is that it either involves unmanageable transaction costs, or an unmanageable principal-agent problem. Either every single creator has to be directly involved in the bargaining, which can't realistically be done, or the creators have to empower some small subset of them as bargaining agents, which means the rest of the creators get screwed by those agents.
