When people learn that I want to replace the welfare state with a universal basic income, or UBI, the response I almost always get goes something like this: “But people will just use it to live off the rest of us!” “People will waste their lives!” Or, as they would have put it in a bygone age, a guaranteed income will foster idleness and vice. I see it differently. I think that a UBI is our only hope to deal with a coming labor market unlike any in human history and that it represents our best hope to revitalize American civil society.

The great free-market economist Milton Friedman originated the idea of a guaranteed income just after World War II. An experiment using a bastardized version of his “negative income tax” was tried in the 1970s, with disappointing results. But as transfer payments continued to soar while the poverty rate remained stuck at more than 10% of the population, the appeal of a guaranteed income persisted: If you want to end poverty, just give people money. As of 2016, the UBI has become a live policy option. Finland is planning a pilot project for a UBI next year, and Switzerland is voting this weekend on a referendum to install a UBI.

The UBI has brought together odd bedfellows. Its advocates on the left see it as a move toward social justice; its libertarian supporters (like Friedman) see it as the least damaging way for the government to transfer wealth from some citizens to others. Either way, the UBI is an idea whose time has finally come, but it has to be done right.

First, my big caveat: A UBI will do the good things I claim only if it replaces all other transfer payments and the bureaucracies that oversee them. If the guaranteed income is an add-on to the existing system, it will be as destructive as its critics fear.

Second, the system has to be designed with certain key features. In my version, every American citizen age 21 and older would get a $13,000 annual grant deposited electronically into a bank account in monthly installments. Three thousand dollars must be used for health insurance (a complicated provision I won’t try to explain here), leaving every adult with $10,000 in disposable annual income for the rest of their lives.
