I have seen this argument often. My main difficulty in employing it in economic policy debates is my inability to articulate an example of a successful country that has not employed a minimum wage policy. Any country that has no minimum wage requirement seems to be of the third world persuasion. I write this reply not because I disagree with you but hope you can aid me in finding a successful example of a 1st world country without a minimum wage requirement and lift my ignorance.
In case you haven't noticed, first-world countries are failing right and left.
