Currently 36% of US adults are obese. Don't you find strange, that such a rich and developed country can't solve such a simple problem?
I have heard that rich people are usually less obese, but not sure. Anyway, even very poor people now are richer than people 300 years ago.
I want to speculate, that this situation illustrates the fundamental problems of our civilization: the humanity is like an anthill, where everybody uses narrow specialization for earning money, and a global administration does not exist. What do you think?
