Riddle me this Batman: if nearly one third of all people in this country are over weight, then how come I can never find fat guy clothes? This is supposed to be the greatest capitalist nation in the world right? So what happened to the law of supply and demand? The demand is out there, just go to Wal Mart at 3 am and you'll see it. Sadly, most fat people are there because that is one of the few places a big guy can get his kit on.
Walk around the mall sometime, and look at all the stores that cater to super small people. It's mind blowing, and it also flies in the face of logical sales strategies. Maybe the thinking is that heavy people are down on their appearance so they shop less, whereas skinny people are vain and go out and buy a ton of shit they don't need. I don't know, but I do know that you can't find half the shit in a XXL that you can find in a XXS.
