Now we're supposed to be sad for Kendall Jenner because she says it's hard being famous. Making lots of money is a burden. From People:

Kendall and Kylie Jenner share the spotlight with their famous older siblings, but only they know what it's like to grow up in the media glare - and they admit it's not easy.

"They got to live their teen years in a very different way than we did," Kendall, 18, told PEOPLE. Kim Kardashian and her sisters, Kourtney and Khloé didn't become famous until they were in their 20s, she explains. "They lived it normally and then once they were already grown up, they went through what we're now going through. They even say to us: 'If I was in your position, I would not be able to handle it.' "
In my opinion, they wouldn't know what a normal life really is, since their version of normal is being in front of the camera. My guess is that they don't even know what they're missing, and if they were put in our shoes instead, they'd be groaning. We smell the Kardashian marketing engine at work here.
