There’s a simple way to end poverty: the government just gives everyone enough money, so nobody is poor. No ifs, buts, conditions, or tests. Everyone gets the minimum they need to survive, even if they already have plenty.

World Changing Ideas: This is part of Co.Exist’s annual collection of some of the most interesting and thought-provoking trends that will alter the world in the year ahead. See the whole list here.

This, in essence, is “universal minimum income” or “guaranteed basic income”–where, instead of multiple income assistance programs, we have just one: a single payment to all citizens, regardless of background, gender, or race. It’s a policy idea that sounds crazy at first, but actually begins to make sense when you consider some recent trends.

The first is that work isn’t what it used to be. Many people now struggle through a 50-hour week and still don’t have enough to live on. There are many reasons for this–including the heartlessness of employers and the weakness of unions–but it’s a fact. Work no longer pays. The wages of most American workers have stagnated or declined since the 1970s. About 25% of workers (including 40% of those in restaurants and food service) now need public assistance to top up what they earn.

The important thing is to create a floor on which people can start building some security.

The second: it’s likely to get worse. Robots already do many menial tasks. In the future, they’ll do more sophisticated jobs as well. A study last year from Carl Frey and Michael Osborne at Oxford University found that 47% of jobs are at risk of computerization over the next two decades. That includes positions in transport and logistics, office and administration, sales and construction, and even law, financial services and medicine. Of course, it’s possible that people who lose their jobs will find others. But it’s also feasible we’re approaching an era when there will simply be less to do.

The third is that traditional welfare is both not what it used to be and not very efficient. The value of welfare for families with children is now well below what it was in the 1990s, for example. The move towards means-testing, workfare–which was signed into law by Bill Clinton in 1996–and other forms of conditionality have killed the universal benefit. And not just in the U.S. It’s now rare anywhere in the world that people get a check without having to do something in return. Whatever the rights and wrongs of this, that makes the income assistance system more complicated and expensive to manage. Up to up to 10% of the income assistance budget now goes to administrating its distribution.

For these reasons and others, the idea of a basic income for everyone is becoming increasingly popular. There has been a flurry of reports and papers about it recently, and, unusually, the idea has advocates across the political spectrum.

The libertarian right likes basic income because it hates bureaucracy and thinks people should be responsible for themselves. Rather than giving out food stamps and health care (which are in-kind services), it thinks people should get cash, because cash is fungible and you do what you like with it.
