Concentration of individual wealth
Unnecessary personal wealth
Those with more wealth are able to make more out of it, to extend their power through investments which give them control over important economic decisions.
In the first place, it is obvious that not only is wealth concentrated in our times but an immense power and despotic economic dictatorship is consolidated in the hands of a few, who often are not owners but only the trustees and managing directors of invested funds which they administer according to their own arbitrary will and pleasure. This dictatorship is being most forcibly exercised by those who, since they hold the money and completely control it, control credit also and rule the lending of money. Hence they regulate the flow, so to speak, of the life-blood whereby the entire economic system lives, and have so firmly in their grasp the soul, as it were, of economic life that no one can breathe against their will. This concentration of power and might, the characteristic mark, as it were, of contemporary economic life, is the fruit that the unlimited freedom of struggle among competitors has of its own nature produced, and which lets only the strongest survive; and this is often the same as saying, those who fight the most violently, those who give least heed to their conscience. This accumulation of might and of power generates in turn three kinds of conflict. First, there is the struggle for economic supremacy itself; then there is the bitter fight to gain supremacy over the State in order to use in economic struggles its resources and authority; finally there is conflict between States themselves, not only because countries employ their power and shape their policies to promote every economic advantage of their citizens, but also because they seek to decide political controversies that arise among nations through the use of their economic supremacy and strength.
