A recent article in the Economist discusses minimum wage laws. Some representative excerpts about the current state of empirical evidence include: "... minimum wage has done little or no harm..." and "... a moderate minimum wage probably does not do much harm and may do some good...".
This hardly seem like a ringing endorsement of minimum wage laws to me. I interpret the article as basically saying that this particular government intrusion and loss of freedom at best has little effect other than to increase the size and power of government and limit freedom of the populace.
While that seems like a bad thing to me, many are thrilled to know that their favored approach of having the government do as much as possible is probably not going to screw things up too badly in this particular instance. The Economist, for example, seems quite happy with minimum wage laws.
