Here's some evidence for you. You should look into the tragedy of American Samoa that resulted from the law raising the minimum wage. Basically, the US Congress raised the wage and the tuna canneries decided it was cheaper to build automated plants. It was an economic holocaust. Recently the US government delayed a further increase because even they admit this caused very high unemployment. Of course, it's too late: the new canning plants are built now.

Here's what minimum wage laws do: they make all jobs that pay less than the new minimum illegal. That's precisely and exactly what it does. A law that says all jobs must pay $15/hour, makes all jobs paying less than $15/hour illegal. It does nothing to change the economics of whether the job is *worth* $15/hour because it provides that much value. Simple logic will show that a minimum wage law can only increase unemployment.

If minimum wage laws worked, then why are the supporters of these policies so stingy? Why not have a $100/hour minimum wage? Why not $10,000?
