On the bright side, the immediate devastation of low wage jobs would slow illegal immigration.
Alas, it would probably have the opposite effect. If you are law abiding but young and unskilled there won't be a job for you. But the work will still need to be done, so more jobs will be created in the underground economy.
Minimum wage doesn’t destroy the need for labor it causes inflation. The people on Free Republic sound like idiots when the talk like this. The discussion should be about inflation caused by minimum wage increases.
