No real surprises. And doesn't Kroeger own Fred Meyer? http://money.msn.com/investing/5-companies-paying-americans-the-least
As BP noted, no surprises. They are firms that require on a percentage basis the most low-skilled labor. One item the article states with which I vehemently disagree is raising wages in concert with profits. The labor wage is the labor wage. We no longer have slavery; people are free to accept a job or decline one. The company is owned by the shareholders; it is to them that the management has allegiance. It is their job to protect their long term interests.
Gee, who would have thought that companies that basically have no barrier to entry other than you're not a criminal and not a druggie won't pay that much.
