It's a huge problem. I have watched very little American media produced in the last decade because of this. Whenever some coworker talks about how great this new show is, I'll watch it and cringe. It's 90% an A-plot B-plot following the same tired template. Then 10% of it is doing some form of virtue signaling, grievance agitation or other propaganda technique to rile the plebs. I can only imagine people who watch it are desperate for any sort of escape from reality.
Outside the US, at least other countries play with different storytelling techniques. France with their 85 plots in a single story and Korea with their strong single plot driven by the main character's emotion. Plus, thankfully Japan's entertainment industry is going strong by having the different mangas compete with each other until the most interesting stories get adapted into an anime.
