You’re repeating the myth that we have to keep food-stamp-wage jobs because they are better than nothing. They are not.

Less than living-wage jobs transfer the costs of the business to the taxpayer in the form of government subsidies to the affected employees for food, housing, medical care, etc. They both increase the size and cost of government and they depress the standard of living of both the employees and the taxpayers.

If every employer is forced to pay a living wage the market will adjust. New jobs and new businesses will appear because people still need things. The jobs may be in delivering the machines, marketing the machines, maintaining the machines, repairing the machines, etc.

The assumption that the difference between $9/hr and $15/hr is sufficient to always displace the worker with a machine is almost always false because machines are very expensive. The assumption that the person who had the $9/hr job that was replaced by a machine will never work again is also false.
