It's highly constructive when the prevailing mode of discussing the issue blames public policy and business practices, as this article does. I stand by my assertion that it's mostly personal failings. Therefore, nothing needs to be done. It's a free country. Let people make their choices and suffer the consequences.
I'll make allowances that agriculture policy (subsidies for grains and soy) and bad diet advice from the government probably play a role. But it's not the predominant issue.
