Much attention has been given in recent years to what might be called the "higher organization" of the state, both in the practical experimentation of modem nations and in the domain of theoretical analysis. In almost every country in the world there has been experimentation with and discussion of the emerging evolution of political-economic forms and forces, now everywhere challenging the peace and security of mankind technology, cartels, unions, business and agricultural associations, armies, professions, churches, schools. The problem of a socialistic or a mixed economy has led to vigorous debate not only upon economic principles but upon the whole political setting of economics.
