This leads to the standard Republican riposte: Just don’t subsidize demand. Keep the government out of it. Let the market work its magic. That’s fine for goods where access is not a matter of justice. If virtual-reality headsets are expensive, well, so be it. It is not a public policy problem if most households cannot afford a VR headset. But that cannot be said for housing and education and medicine. Society cares about access to these goods and services, as well it should.
