A free market, and the belief that the market will continue to be free, is all the encouragement savers ever need. All economic gains must be eventually shared. This is not socialism. It is the essence of the free economy. It is plain distribution, or diffusion of wealth.
All business is done by agreement of some kind.
The agreements are voluntary. Nobody agrees to anything unless he finds it in some way to his advantage. These add together to make the essential reason why economic well-being is more widely distributed in the United States than it ever has been in any other country. For in a free economy, everybody gets a share of the values other people have to offer. But they also have to share a part of the values they themselves have to offer.
