If someday we needn't work......

If one day we don't need to work any more,then people would have a lot of leisure time.They have nothing to do.First they play and enjoy the time.but day day after,they find it very boring. No one to talk about,nothing to talk about,then a lot of problems arise because of plenty time avilable.Like gambling,like robbery. So they decide that,we'd better return to work again!
