True enough but Wal Mart is nearly 100% a chinese junk shop. They're the ones who really planted the chinese flag here and for a company that represents 2% of the GNP, they're place in the market swamps all the rest that you listed...combined.
If you want to shop at Walmart, be my guest. I'm forced to go there occaisionally, and I hate every second I'm there. (yes forced...I'm 30 years married and have learned to sometimes just do what I'm told) But don't pretend that they're some great bastion of free market conservative values. They're not.
I just bought a nice gift for my adult daughter at Walmart. Made in USA.
