Does Everyone Cook?

In the last 3 days I've seen a cooking show hosted by Valerie Bertinelli (with her friend, actress Faith Ford added in for good measure), Neil Patrick Harris and David Burtka on an episode of In the Kitchen with Ina, a cooking show hosted by Trisha Yearwood, a cooking show hosted by Tiffani Amber Thiessen, and a cookbook written by Freddie Prinze Jr. (with a foreword written by his wife, actress Sara Michelle Gellar thrown in for good measure.)  All of that brings me to my question - Does everyone cook?  Why is it when people get famous, the next logical step is to host a cooking show or write a cookbook?

Surely, most of Hollywood uses their hundreds of thousands, or in some case millions of dollars to hire personal chefs so they don't actually have to cook.  I actually like to cook, and I still admit that I would totally do that if I hit the lottery.  Because of this, I feel like most of Hollywood is out of practice.  Therefore, they can't be that stellar in the kitchen to warrant a whole show dedicated to their cuisine.  

Also, there was a time that cooking shows and cook books had themes - Mexican food, Italian food, 15 minute suppers, you get the drift.  Anyway, what is the theme of these cooking shows being hosted by these very famous people? Food cooked by famous people? Where's the theme people!? I'd rather eat yummy food than famous food.

Now that that's off my chest, I'm begging you Hollywood - please leave the cooking, baking, hosting and writing to the professionals and the fabulously talented home cooks that deserve a shot more than you do.  You've made your millions already, leave the cooking millions to those that deserve them, and those that actually cook for themselves on a daily basis.  They know much more about food than you do anyway...
