But this isn't just "I don't like these shows", it's "no one likes these shows, sometimes they are cancelled before the first season even finishes airing"
I think they would be in a better bargaining position if more shows weren't getting absolutely trashed by both critics and audiences over their writing, that's all.
What it seems like you are really asking for is that no or not many shows are canceled, or they all or most shows appeal to you / everyone. I don’t think that has been possible since the invention of cable, or certainly since the invention of YouTube.
There is too much content out there to waste time on content you don’t like. Honestly it’s a huge win for basically everyone.
Additionally every new show is competing against every show you’ve ever liked (including canceled shows) since they’re no longer relegated to reruns and syndication. You can probably get the whole series on DVD for a way lower price (I remember when each season of X Files was like $80 on DVD) or on a streaming service.
There are still new “mass appeal” shows and movies —- they are often panned as being broad, formulaic slop but they still do crazy numbers. Maybe it’s not actually hard to make content that appeals to most people, but maybe that’s not most content creators’ intention.
Every show gets canceled eventually, except Jeopardy and The Simpsons I guess. The studio still owns the IP and can re-release, reboot for as long as human life exists.
Industry never wants to raise wages for anyone! A handful of companies own all TV & film media, meaning it’s even harder for folks to negotiate. That’s why unions and strikes are necessary.
