In response to "Fat kids are your fault", it is definitely unfortunate that parents cant see the error in their ways when it comes to what they're feeding their children, and ultimately, responsibility for each child being obese falls on his or her parent. But this is not what "Crap Food & Childhood Obesity" was about.
"Crap Food & Childhood Obesity" was more about the lack of transparency in the government when it comes to the kinds of things they are subsidizing. You cannot argue that children are getting bigger and bigger, and there is a reason other than their parents are making bad choices, the fundamental problem with the picture is that junk food is cheaper, more advertised and more readily available than a healthy meal.
There is no reason we should spend such a gross amount of money helping companies get rich off making America more unhealthy, would it make sense to spend a few billion dollars helping Marlboro make cigarettes cheaper? Because as of 2010 obesity related deaths outnumber tobacco related ones.
