Walmart jobs are aimed at the part timer, retired, and second income population. No primary breadwinner would have any rational hope in a Walmart job. (Unless a store manager). That's just the way they are. Maybe to hope they could ever be anything other than the McDonalds of retailing is vain.
Like I wrote: I don't think Walmart would be such an issue if we had an expanding middle income jobs like in manufacturing. But many people feel they are declining (that is the perception anyway) and Walmart is seen by many rightly or wrongly) as the only employer in town these days. That is the real issue but people are distracted away from that to talk of Walmart wages. If Ford and GM were expanding and hiring this would not be an issue.
Tripe like this just makes me wanna go buy more stuff at Wal Mart.
