Megan McArdle notes the problem with the government providing guaranteed income for people - people don't do well.
I’ve sat on a lot of panels on this topic, and inevitably someone waxes lyrical about the creative possibilities that will be unleashed by a universal basic income, the opportunities for art, community service, political activism, cultivation of family and friends. This is, needless to say, completely divorced from the actual experience of communities with high rates of long-term dependence, whether they are American communities where Social Security disability has become a substitute for long-gone industrial work, or European countries with a long-term dole.
Being out of work makes people unhappy and depressed, even when they have an income stream to take care of their basic needs. What those unhappy depressed people mostly increase when they are out of work is their sleeping and television-watching; during the great recession, volunteering, education and exercise basically didn’t budge.
