Actors and Writers are the only content creators with draconian guild rules that prohibit low cost content creation.
In the 70's and 80's stars and writers had the leverage.
Seems like today they have competition with high quality Sports, reality TV, cinematic documentaries, YouTube, and social media.
and none of those other creators have any guild rules.
The business, and the leverage has changed.
The streamers ruined the business, and the content boom is over. Couldn't be a worse time to make demands imho.
