@wopchop above.......
The minimum wage is a restraint on the free market; so are paid vacation mandates, statutory holidays, parental leave and a 40 hour work week (44 hours in Ontario).
We do have these restraints, and they are effective to a point in providing a better minimal outcome for all workers. I would argue they are inadequate, and that we ought to have higher minimum wage, higher paid vacation mandates and a personal day (sick day) mandate as well.
Worker safety laws as a restraint on the market as well; so are interest rate caps and building codes and fire codes, and accessibility mandates.
The idea that there is or should be an unfettered free market borders on the incredulous to me.
