I think raising the minimum wage to what it would be if it had kept pace with inflation would have little, if any, negative impact on jobs and the economy in the short term. But I also think it would do little to solve the question of how to deal with a large segment of society that simply does not have the ability to compete with technology for livable wages.
The answer is to tell them to get out of the business of selling their labor and to get into the business of solving problems. John Henry demonstrated that competing with a machine at simple labor isn't a good way to make a living. But Edison showed that same perspiration applied to coming up with new mechanisms to serve man can change the world.
As long as we have problems, we'll have jobs. Future jobs will require less labor and more ambition.
