There is greater pressure on the middle and upper class to be thin. And they have greater resources to achieve that. And there is discrimination against larger people in the work place which may deny them income.

Obesity also correlates strongly with church attendance. Some have theorized that there are few comforts affordable to those of lower income. But 2 comforts they can afford are church and food.
