I appreciate what you are saying, but just wanted to point out that Mathers is only a tiny cog in the machinery. You should be more enraged that there is a multi-million dollar record company recruiting and promoting this garbage, and even more concerned that there is a market willing to pay good money for this crap.
You're too kind to the record companies. Their goal seems to be to find recording "artists" who will do anything to gain fame and make a buck. I figure it's because their goal is to sell more records, and if they can get impressionable kids to buy this junk that sounds awful, they won't listen to it much and the stars will fade before they can demand the big bucks that groups like the Stones, Aerosmith, etc. do. It must be much easier for the companies to deal with untalented commercial twerps who have no interest in evolving.
Want good music? Go to the small venues. That's where you'll find good music, from talented, developing artists who haven't sold out!!
