At least with the studio system, the owners of the studios were lending out the resources for artists to do the cultural production. Obviously we're adults here so explaining why letting people use capital so they can produce stuff for you to sell is exploitative isn't necessary, but at least that's a model that propels some level of cultural development because you're socializing production (but privatizing gain). I think the general trend with social media has been to dismantle the capacity to create art or interesting media because it boosts all the structural forces inherent in capitalism that impede genuine expression, creativity, and leisure without any kind of upside beyond the globalization (which is kinda meh since, other than anime and kpop, it seems like audiences aren't rushing to consume tons of cultural exports from countries other than the US via the internet).
