The problem is that the vast majority of people don't have minds of their own. People listen to whatever is popular, and what's popular is whatever the money people decide to make popular. In the 60's you had payola. After laws were made to prohibit that somewhat, the hoods who use to just own record companies started buying radio stations too by the dozens and they were darn well gonna play their own artists. That's why when you drive across the country you'll find the exact same artists and songs on the radio.
Now with digital downloads, don't think that the same record companies aren't paying places like YT and Spoitify to "suggest" certain songs to people in their news feeds.
Only small genres like folk and bluegrass are truly independent today and that's only because they're small niche markets that don't sell enough units to interest the hoods.
The real heart of the matter in my opinion is that bad people outnumber good people in this world by a large margin.
