"And what is the "complete picture" ..."

well, the picture is that Walmart is clever enough to do 'good' things for those in their employ and to give to local charities...etc... That is, those who might have any serious influence on them, while doing BAD things to workers in foreign countries whom you don't hear much from.

There IS also the list of smaller retailers in some smaller towns who were forced out of business by being underpriced by Walmart.

There is no denying that Walmart has good 'business model', if all you care about is piles of cheap merchandise and decent jobs for a few who will keep their mouths shut and pretend the bad aspects don't exist.
