No, I'm implying the lifestyle of being lazy and fat. Frankly, the cross we bare is a self-inflicted burden. With the rampant corruption going on at the FDA, not to mention the idiots calling shots, it's not entirely someone's fault if they display somewhat poor eating habits.
I think you're envisioning a utopian society where everyone is fit, intelligent, moral, wealthy, communicative, and peaceful. Let's face it - man is man because of inherent errors. People are going to slip through the cracks. If we educate people about the simplistics of nutrition (and it is very easy), they can make better choices, and make this pandemic cut down. Having said that, I have no problem helping someone who's willing to help themselves. If someone got pretty heavy and wanted to make a commitment to change their sedentary lifestyle, sure - give them a helping hand. After all, it's not like getting a gastric bypass or a lap-band is an instant cure-all. They don't wake up the next morning perfectly healthy. It's a tool to help achieve a goal - a goal they still have to try for.
This is an extremely slippery slope you're heading down. Next, it may be removal of college loans and reverting back to the day where only the rich go to school.
Use of public funds is not, in an of itself, an evil or amoral act. Abuse of it is.
