So a kid is fed McDoubles and hot dogs for dinner every night from age 2 to 14. He's severely overweight by the time he's 6, and then has trouble clawing out of the pit when he reaches adulthood. That's his fault?
A mom feeds her kid McDoubles and hot dogs for dinner every night. She doesn't have a spouse to help raise the kids or provide additional income, she works two jobs at minimum wage, and she doesn't have the time or money to cook healthier meals for her child. Personal decision-making is the only thing that's at fault here?
I mean, I know I'm being a pain, but obesity rates are ridiculously high and have grown over the last few decades. I don't think it's because people are getting dumber or more irresponsible. Things are changing in society. Individuals should be accountable for themselves, but I think we're being willfully ignorant of some things if we accept that it's really that simple. And to be honest, if you've never found yourself on the overweight side of things, it's hard to understand.
Well technically that's still due to "personal decision making", just the personal decision of the mother (particularly in case 1). I said 90% because that's how much I would put to personal decisions (by either the person themselves or their caretakers), with the other 10% being factors such as genetics, the food industry, availability of healthy foods, etc.
