I used to say the same things but I changed my mind a while ago. A lot of people like simple things with great productions and would rather dance and have a good time rather then be educated. No fault to them, that's just the way it's been since forever. Most of the time people listen to music to feel better and most pop is bubbly feel good. And if you really think Pop music has gotten bad go watch the top 100 songs of the 2000's on VH1 and be like, "damn, wth am I talking about, I remember these"
There are good Pop songs but they just come out a lot less frequently. And if you're adamant about it, of course you're never going to hear them. Also there are still creative Pop songs coming out, of course there is still going to be sampling and borrowing we live in the digital age. And if you claim you're original, you are not. This applies to all aspects of life; cooking, clothing, architecture, etc.
And it has less to do with looks then you think, e.g. Adele, Lady Gaga, nor Ke$ha wouldn't be popular. Neither would Jay-Z, Drake nor Train.
