More recently, in a 2006 book, conservative intellectual Charles Murray proposed eliminating all welfare transfer programs, including Social Security and Medicare, and substituting an annual $10,000 cash grant to everyone 21 years and older. The Alaska Permanent Fund, funded by investments from state oil revenues, sends annual dividend checks to the state’s residents. Switzerland is voting on an unconditional basic income later this year. (Though the fundamental basic-income guarantee involves an unconditional grant to every citizen, no matter their wealth or age, other versions wouldn’t cut checks to those in top tax brackets or those receiving Social Security.)

Apart from lifting millions out of poverty, the plans promote efficiency and a shrinking of the federal bureaucracy. No more “79 means-tested programs.” Creating a single point of access would also make many recipients’ lives easier. If they knew they had something to fall back on, workers could negotiate better wages and conditions, or go back to school, or quit a low-paying job to care for a child or aging relative. And with an unconditional basic income, workers wouldn’t have to worry about how making more money might lead to the loss of crucial benefits. In the Financial Times, Martin Wolf has contemplated a guaranteed income’s ability to help society adjust to the disappearance of low-skill, low-wage jobs.
