Of course. But what's that got to do with anything? Overhead doesn't vary. Wages don't vary. They never know exactly what their profits will be, but they do know exactly what their expenses will be. So logically, if that number goes up, the number they have to make to avoid losing money goes up. They could theoretically make more gross revenue, atleast for a short honeymoon after the law passed, because alot of people would have twice as much money to spend. But the effects on business would be far reaching. Most businesses operate on a 5 to 6% profit margin, after subtracting wages, rent, utilities, wholesale merchandise, and taxes. Walmart operates at 3%. The reason they make billions is dealing in bulk sales. They have 5500 stores worldwide. But vast majority of their employees are close to minimum wage. If history is a guide, and they stay anywhere around the historical profit margin, how can they stay in business under the proposed $15 an hour wage without raising prices or laying people off or both? Furthermore all of their vendee and wholesalers would also be affected in a similar way, so if they have to likewise raise prices, that adds more to Walmart's overhead. I have no issue with people making more money, I'm just saying it's a more complicated issue than just pronouncing a new minimum wage. If once the market adjusts, $15 only buys what 7.25 used to buy, then what purpose did it serve?
