X Factor: You're wasting your time

Interesting to note that the X Factor is getting Katy Perry and Robin Thicke in next week.

For a show that is supposedly suggesting that fame is down purely to talent, curious that the actual singers they turn to both owe their careers to famous parents.

After 10 years of identifying people with this X Factor, shouldn't there be a big pool of internal celebrity, more than large enough to fill every slot that calls for a big name?
