All of the progress that the US has made over the last couple of centuries has come from unemployment. It has come from figuring out how to produce more goods with fewer workers, thereby releasing labor to be more productive in other areas. It has never come about through permanent unemployment, but temporary unemployment, in the process of shifting people from one area to another.
Milton FriedmanA society that puts equality - in the sense of equality of outcome - ahead of freedom will end up with neither equality or freedom. The use of force to achieve equality will destroy freedom. On the other hand, a society that puts freedom first will, as a happy by-product, end up with both greater freedom and greater equality. Freedom means diversity but also mobility. It preserves the opportunity for today's less well off to become tomorrow's rich, and in the process, enables almost everyone, from top to bottom, to enjoy a richer and fuller life.
