One thing you forgot to mention... since Walmart has no "affordable heath insurance" for their employees and most of their regular strore employees are below the poverty line, they tell their employees (as was atested to by several x walmart managers and employees and current employees) to go on Government supported healthcare... the healthcare for needy families and welfare families. Their rationale is "That's why the government health care is there, so use it". In other words... let the taxpayers pay for your health insurance.

They offer low cost items, but what is the ultimate cost of "Low Cost"?

The jury may be out in some places, but some countries (like Scotland for example) have kept them out (even after trying to change their name and re-open) to save their "mom and pop" based economy.
