The policy of letting things alone, in the practical sense that the Government should never interfere with business or go into business itself, is called Laisser-faire by economists and politicians. It has broken down so completely in practice that it is now discredited; but it was all the fashion in politics a hundred years ago, and is still influentially advocated by men of business and their backers who naturally would like to be allowed to make money as they please without regard to the interest of the public.
