It is not merely that the ownership of any substantial share in the national wealth is concentrated to-day in the hands of a few hundred thousand families, and that at the end of an age which began with an affirmation of the rights of property, proprietary rights are, in fact, far from being widely distributed. Nor is it merely that what makes property insecure to-day is not the arbitrary taxation of unconstitutional monarchies or the privileges of an idle noblesse, but the insatiable expansion and aggregation of property itself, which menaces with absorption all property less than the greatest, the small master, the little shopkeeper, the country bank, and has turned the mass of mankind into a proletariat working under the agents and for the profit of those who own.
