The US tax system favors introducing machinery instead of people. If you hire people, you pay 30 percent tax. If you hire machinery, you pay zero tax. These are the kinds of things that we can easily change in order to alter the direction of research, the direction of innovation in the market economy. I would get rid of the excessive incentives for replacing labor, and create new incentives for technologies that can create new tasks, new competencies.
