Absolutely correct. However in middle America these days, I'd say 99% of the BIG people are FAT. And the so-called "poor" people are among the fattest.
Well, I have been on that end of things too - pretty well lost the use of my legs in my 40's, lost everything, sat in a chair for 7 years, and ballooned way past 400lbs... On one meal a day... So I ain't so quick to judge.
