The thing is, the first wave of people who were obese as children haven't quite gotten old enough to start dropping dead. Once that happens, there will be panic and backlash. Right now, people assume obesity is something that kills you in your 60s - that's if you got obese at age 40. If you're obese at age 10, you'll drop when you're 30. Soon... very soon these people will start dying and the consequences will be terrifying.
