What are you going to do about it? The people like it enough to buy it. Who are you to tell them, 'nope, this is objectively bad, you can't have this'? Why is it such an issue for you to let them alone with their beloved simple music?
While we're at it, why not take on the literature industry? We seriously have to do something about people buying these Twilight Books. Sure they like them, but that's only because they're too stupid to not like the Greek classics. We need to take these publishers down!
And there is a huge quantity of amazing music being made right now. The idea that it's been drowned out is absolutely absurd and either ridiculously ignorant or intentionally false. There has been an absolute explosion of originality in the last decade.
And there has always been 'focus group stuff' for teenagers, too. Elvis was a marketed product for God's sake, he didn't play guitar or write songs.
If there are plenty of people like you out there looking for it then obviously they can sell you and lots of other people music and merch and gig tickets.
Again, what are you going to do? Force people who don't know better to listen to what you think is good music?
