"The tendency of money to depreciate has been at times a weighty counterpoise against the cumulative results of compound interest and the inheritance of fortunes. It has been a loosening influence against the rigid distribution of old-won wealth and the separation of ownership from activity. By this means each generation can disinherit in part its predecessors' heirs; and the project of founding a perpetual fortune must be disappointed in this way, unless the community with conscious deliberation provides against it in some other way, more equitable and more expedient."
