If you do that, then performers will just exert their power in other ways (by reducing royalties for song-writers). Fundamentally, this is happening because the quality of the song-writing isn't really all that important to the success of a pop star. Marketing, production quality, and sex appeal are more important. It's really not that hard to write a 4-chord song about breaking up with your boyfriend. If song-writers think they should be getting rich off these popular songs, there is nothing stopping them from performing the song themselves. They don't do that though because they know they'll make more money letting Taylor Swift sing it.
