Walmart Health Insurance: Dream or Nightmare

What if Walmart decided to provide health insurance for all of its 1,200,000 employees instead of only 500,000 of them? Wouldn't that be a nightmare for health insurance providers, negotiating rates with Walmart? Damn, I want them to negotiate my health insurance rates! Since most of their competition already provides health insurance for most of their employees and since Walmart does as much busines as all of them combined, I would submit that Walmart can provide health insurance for all its employees and still make $256 billion a year. Want to cut taxes? Make Walmart pay for its employees health insurance instead of Medicaid.
