That's insane. My health insurance premiums go up 15-20% each year because of other people's expenses, not because of mine. Who do you think pays for the uninsured care hospitals and doctors give out free? Right, people who have insurance.
That isn't the fault of fat people. It's the fault of politicians that you support. You are the problem with rising insurance rates because you along with the politicians you support mandate that healthy industrious people that pay for their own health insurance also pay for lazy unhealthy peoples health insurance. In short, fat people aren't the problem, you are the problem.
Taxing junk food isn't going to lower the cost of health insurance or make anyone healthier. It's just going to send more money to Washington for the politicians to flush down the toilet.
