Why are most blonde's prettier than brunette's?

I've always wanted to be a blonde. I wish I looked like Kate Bosworth or Carolyn Murphy. They are so beautiful. I've always been very self - conscious about my hair and myself. I've always felt that the beautiful blonde's got all the beautiful brunette guys. I don't want to look like a star blonde or a trashy looking blonde like Pam Anderson. I think those blonde's are gross. I would rather be brunette than look like Pam Anderson.
