Also, with the implementation of Obamacare, states that bought into BOb's expanded Medicaid program will include people up to 133% of the federal poverty level. So under your theory, beginning in 2014 wages should drop at Wal-Marts in states like California that bought into the expansion relative to states like Mississippi that didn't buy into it, right? I'll entertain a friendly wager on that if you want. I noticed that right across the border in Canada, which has national health insurance, Wal-Mart tends to pay workers MORE than it pays in the U.S. For example, according to Glassdoor a "completely subsidized" night stocker in Canada makes an average wage of $12.48/hour, well above the country's minimum wage, while in the U.S. the "low-subsidized" U.S. equivalent earns $9.60.
