If you want to get even simpler, down to the most basic reality: Wealthy nations like America statistically tend to have employed citizens who can afford to feed themselves to the point of obesity. That's why you see so many of them. It's hard to get heavy when you are starving and are forced to live off of 160 dollars a month on food stamps.
Libertarians and Republicans refuse to believe that businesses should be capable of failing to the point that people die. They refuse to take responsibility for the deaths caused by such failures. They don't believe in hiring veterans because veterans have spent their life on a federal payroll to cover their occupation [and injuries] in terrorist nations. HOW DARE THEY TAKE GOVERNMENT MONEY IN RETURN FOR ENSURING NATIONAL SECURITY!
