What is wrong with me deciding for myself how much I'm willing to work for? So far, you only posited that it's wrong because the vast majority of other people don't think that way. Is being in the minority inherently wrong, in your view?
I think RKMBrown comes closest to answering this question honestly. Minimum wage is essentially government mandated unionism.
The minimum wage is a way to keep poor people poor so they continue to elect liberals to fix a problem created by liberals.
Hmmm... but isn't that the same thing?
