Obesity doubled in the United States since 1975. If a huge state change like that is observed in hundreds of millions of people in a 50 year time period, I guess one explanation could be that they all independently and personally decided to inflict suffering on themselves. Another explanation is something in their collective environment changed. No hate, it's just that to me, that that your explanation is not the most likely one.
