I agree with you, but shouldn't people who have an unhealthy diet pay for the medical consequences of that diet themselves? I know it sounds a bit hard, but everybody knows that eating a lot of fat food everyday is very unhealthy. Yet some people choose to do it anyway. And they get away with it from a financial point of view because government externalises those costs to you and me. I just think that people should pick up the bill of their own voluntary, informed, unhealthy lifestyle.
