Pollution is only one small part of the over regulation of industry by enviro-whackos through governemnt. And there are also all kinds of other over regulation that has nothing to do with the enviro-whackos. But it is nice to see that you can see that it is not Walmart that is causing industry to seeking cheaper means of production, even though you will not admit it publicly.
However, that still does not address the rest of my comments - you seem to wish to make Walmart the ONLY cause of your perceived problems, when in fact Walmart is probably one of the smallest causes of the problem.
This is a much more complex problem than all the Walmart bashers are willing to admit. You brought up the dollar store chains and blame Walmart for the phenomena of their success - yet I was shopping in those type stores LONG before I ever even heard of Walmart - and they were selling "made in China" stuff long before Walmart was. They were paying their employees crapola wages back then and generally continue to pay their employees less than Walmart.
I get such a kick out of you folks that insist Walmart is evil incarnate forcing all the manufacturers in the US to outsurce labor to other countries.
Walmart is not the only cause, but as the consumer of 10% of Chinese exports, it's the biggest single one.
