IN A WORLD in which fiscal policy becomes more complex with each passing administration, an alarmingly simple proposal like universal basic income brings all parties into a state of shock. At its core, UBI seeks to give citizens a periodic, no-strings-attached cash grant to do whatever they want. Whether you are rich or poor, from San Francisco or from Bakersfield, every so often you receive a check in the mail for a fixed amount directly from the government. You could spend it all in a one-night extravaganza or save it to buy the car you always wanted—you could even burn the money in a bonfire if you like (though I would not recommend doing so). The fundamental principle behind UBI is for citizens to choose what they want to do with their money, whatever that choice may be.
