walmart is a scapegoat for a flawed monetary policy.
A scapegoat and a symptom of the sickness of our financial system.
If labor is cheap elsewhere, and politicians are willing to sign trade agreements that make it more profitable to use cheap overseas labor, of course a corporation that is in the business to make as much money as possible is going to exploit every advantage they can to do so more successfully than its competitors.
Perhaps it could be argued that Wal-mart has gotten large enough that it isn't simply exploiting advantages, but driving the policies. I'm not sure of that, but it has gotten damn large.
I'm not against most of what Wal-mart does as far as having a huge, all your needs in one place, superstore. They built it, the market wanted it. All that does is increase efficiency. The mom & pops go out of business. But did we really need 25 places in town to buy shoes? Instead of 25 shoe stores, people are getting everything they need in one place, a few specialty stores serve the niche and luxury markets, and the rest will move on to doing something else. The economy can evolve. Just because a bunch of shoe salesmen lost their job doesn't mean that the new more efficient US economy isn't creating NEW jobs in NEW sectors (like e-commerce, data systems, alternative energy, robotics, giant catapults, whatever the market calls for). If net jobs and productivity are LOST, it isn't wal-mart's fault, it is a complacent workforce that doesn't adapt and doesn't keep up with matching ingenuity. When America became the dominant economy in the world, it was because of productivity, efficiency, and ingenuity.
