I don't care about the airlines, they're increasing medical costs for the whole system. Obese people have a greater incidence of injury and illness than the non obese population. When the percentage of obese people increases, it furthers the strain on the medical system. This ends up increasing costs and wait times while decreasing quality of service.
You're not wrong, but causality is REALLY hard. What about the obese person who got that way from taking prescribed corticosteroids for a malady that was not his fault?
What about people who got that way before they turned 18 because their parents fed them junk every day, and the window of puberty had closed?
What about alcoholics who are compulsively drinking their calories?
I know there are a lot of people who are just lazy and stupid, but good luck proving that to legal satisfaction.
I don't agree with criminalizing obesity, but I wanted to point out the serious strain it puts our system under. Far more than drug use. Perhaps we shod consider regulating foods and/or having harm reduction education around food and eating habits.
You really want the intrusion of a government bureaucracy in your life telling you how much and which foodstuffs, that are perfectly safe when eaten in moderation, you can buy? Think for a while about how this can go wrong, and about what kind of agency you want over your body.
We already have that when it comes to drugs. I'm saying the industry should be regulated better, instead of a free for all. Regulation is not all or nothing.
