You are so wrong jgoins. It's a question of culture and habits. Countries like Sweden and Norway and Denmark (where I live) are rich countries. The average person living in these countries is much richer than the average American.
In the countries mentioned it is out of fashion to be fat, and pupils are tought about dietary habits in school. Healthy food is a big issue here.
I live in the center of Copenhagen, and here you se everybody riding a bike and in the evening most people exercise.
We have got the time and energy - probably because we are not poor.
Generally rich people don't tend to be fat. They can afford healthy food and perhaps they do not need to eat for comfort as much as poor people.
