For many of us small business owners, that 1987 opinion is on the money. The direct and immediate consequence of raising the minimum wage by a bunch is that I'd have to lay a couple of people off, which would be heartbreaking (for them of course, but also for me).
Unskilled labor simply isn't worth very much most of the time, but it's nice to help people get their foot in the door. One of my absolute favorite outcomes for an employee is to have them grow in capacity so that I "have" to pay them way much more than some artificial wage floor because they've developed into a solid contributor.
