填空题 Work is one of society's most important institutions. It is themain mechanism through which spend power is allocated. It provides 1people by meaning, structure and identity. Yet work is a less generous, 2and less certain provider of these benefits than it once is. Since 2000, 3economy growth across the rich world has failed to generate decent pay 4increases for most workers. Now there is growing fear of a less fundamental 5threat to the world of work: the possibility in that new technologies, from 6machine learning to driverless cars, will cause havoc to employment.Such worries have revived interest in an old idea: the payment of an "universal 7basic income" , an unconditional government payment giving to all citizens, as 8a supplement to or replacement for wages. On June 5th Swiss citizens will 9decide in a referendum whether to require their government to adopt a basic income. Finland and the Netherlands are planning limited experiments in whichsome citizens are paid a month income of roughly 1, 000($1, 100). People 10from all points on the ideological spectrum, from trade unionists to libertarians, are supporters. It is an idea whose day may come. But not soon.
