As an accountant for a small business that works on payroll budgets; I absolutely guarantee you that management's response to a significantly higher minimum wage is fewer workers. This isn't theory, this is the real world, where economists rarely spend any time. We'd have few workers and they'd be working harder.

The McDonald's nearest my house has already implemented touch screen ordering to replace minimum wage workers that this push to eliminate low skill jobs will only be accelerated by minimum wage hikes. As the minimum wage rises, the return on technological investments to replace workers only increases. The government is incentivizing job destruction.
