"Seattle venture capitalist Nick Hanauer, Dori Monson debate $15 minimum wage"

One of the more entertaining arguments advanced by Liberals is that a higher minimum wage would greatly benefit businesses but that business executives are too stupid to realize that. Three pieces that bear on that idea:

Adam Ozimek (Forbes), "Are Retailers Missing A Huge Profit Opportunity By Keeping Wages Too Low?"

Robert VerBruggen (Real Clear Politics), "What if Walmart Hiked Prices and Wages?"

Michael Saltsman (Employment Policies Institute), "Why Subway Doesn't Serve a $14 Reuben Sandwich".

This piece by distinguished economist Richard B. McKenzie is generally helpful in refuting the demand to raise the minimum wage: "Why Are There So Few Job Losses from Minimum-Wage Hikes?"

Finally, a better policy for the poor than raising minimum wages would be to tear down barriers to employment. See, for example, "11 Crazy Laws That Keep You From Getting A Job".
