Agree. After all, she was just a girl who wanted to sing. She was probably in the right place at the right time, but must have been good at singing to have been noticed in the first place. The fact that she was marketed and managed properly was not her fault, and very few people of a similar age would have passed that up.
She is effectively paid based on how popular she is and how many people buy her music. If you think she is rubbish then don't mock her, mock the people who have made her what she is, and moreover the people who buy her music or merchandise, or go to her concerts.
