Walmart's Desire To Maximise Profit Cost Over 100 Lives

I signed this. The only reason corporations outsource jobs from one country to anther is for their own competitive advantage. To make more money. In this case it is obvious that it was cheaper to do business elsewhere as the standards of safety were lower. This cost lives. What sort of economic rationale determines that profitability is more important than human life or the planetary survival? Not one to which I wish to subscribe.
