In fact, America's wealth (and our fairly generous welfare programs, despite what Europeans might think) actually enables the massive obesity rates we have, which is one of the main reasons we have lower life expectancies. If Europeans were richer they'd likely be eating themselves to death more like we do (though cultural and other factors play a role too).
You don't think Europeans can afford to eat the cheap crap that makes one fat? Healthy food is expensive, garbage food is cheap. Obesity is a poverty problem in the whole western world.
No it must be that Europeans can't afford corn fed omega-6 beef, corn syrup water and baked extruded corn mush coated in MSG so they have to get by eating real bread, tomatoes and ham.
I grew up in the South. You'll have to kill these people to take away their sweet tea and fried chicken. And that's just one dimension.
