The age in which we live has been called the age of Finance Capitalism. As the scale of industry grows larger and the complications of the market increase, the banker and financier assume an increasing importance in the conduct of economic affairs. Capital for large-scale enterprises cannot be raised from the investing public without the help of wealthy financial institutions which sponsor or underwrite the issues of industrial shares. Such specialised institutions as insurance companies are in control of large masses of capital which is available for investment: the small investors make increasing use of investment trusts of various types, and of other intermediate agencies for the placing of their money; and over an ever-increasing part of the field one form or another of collective investment through large-scale capitalist agencies is replacing the personal investment of individual savings in production enterprise.
