Sorry, I figured it was so simple that you would realize the logical conclusion, but ill explain.
See, Walmart is cutting about 10% of the jobs from Sam's, not all of Walmart, just Sam's. From the articles I have read its about 10,000 jobs. Now, not all of those jobs were making $10/hr and will be just fine finding a new job. Thus the real issue is the lower wage workers that were just getting by. Now, on top of raising their lower wage to $11/hr, they are also increasing other benefits which cost real money. So, those 10k jobs are having those wages spread across far more than 100k people, meaning Walmart is actually spending more money on its new system than what was lost. This is the very foundation of what the Left has wanted by instituting "living wages", and yet here you are being unhappy. So even though many more people are going to have more money, you are unhappy.
