I know of two people who have had gastric bypass surgery through the military (military wives), and got their "excess skin" removed at taxpayers' expense too. It happens all the time where WE pick up the bill for other peoples' poor choices. I'd prefer not to.
Hold up - first of all, it's TRICARE and it isn't FREE. It's insurance, and it's PAID FOR. As a military wife, I can do any danged thing I need that is covered under my insurance plan - just as I hope any of you in the private sector would do. Have I had bypass surgery? No, don't need It. Is it your business if I do? No. Once again, it's insurance and it's PAID FOR.
Secondly, it's CRISCO for crying out loud. It's cake, it's icing, it's a choice. If we really want the government to save us all, should we shut down all bakeries? Perish the thought.
