Here’s my reply – alas, much less eloquent and persuasive than Jim’s reaction – to the sender of that e-mail:
Mr. Bob Keener, Business For a Fair Minimum Wage 
Dear Mr. Keener:
Thanks for your July 19th e-mail featuring quotations from business owners endorsing a higher minimum wage. Five of the six quoted owners boast that their companies thrive by paying none of their workers wages as low as the current federal minimum.
While I don’t question these executives’ motives, I do question their business acumen. They apparently fail to understand that a business model that works for them might not work for all other firms. If, say, world-class chefs Alice Waters and Charlie Trotter testify – correctly – that their restaurants thrive because they charge high prices, this fact would hardly justify substantial price hikes by the likes of McDonalds and Jack In the Box.
Indeed, just as a government-mandated minimum price for restaurant meals would bankrupt many fast-food restaurants – and, in the process, increase consumer demand for meals in some higher-end restaurants that already charge prices as high as the new government-mandated minimum – so, too, would a higher minimum wage make the least-skilled workers unemployable and, in the process, increase employer demand for some higher-skilled workers who already earn wages as high as the new government-mandated minimum.
Businesses (such as those whose owners you quote) that thrive by employing relatively high-productivity and-high-wage workers stand to benefit artificially if their competitors who thrive by employing more low-productivity-and-low-wage workers are hamstrung by a higher mandated minimum wage.
