Keynes on national self-sufficiency

it does not now seem obvious that a great concentration of national effort on the capture of foreign trade, that the penetration of a country’s economic structure by the resources and the influence of foreign capitalists, that a close dependence of our own economic life on the fluctuating economic policies of foreign countries, are safeguards and assurances of international peace

The divorce between ownership and the real responsibility of management is serious within a country when, as a result of joint-stock enterprise, ownership is broken up between innumerable individuals who buy their interest today and sell it tomorrow and lack altogether both knowledge and responsibility towards what they momentarily own. But when the same principle is applied internationally, it is, in times of stress, intolerable – I am irresponsible towards what I own and those who operate what I own are irresponsible towards me. There may be some financial calculation which shows it to be advantageous that my savings should be invested in whatever quarter of the habitable globe shows the greatest marginal efficiency of capital or the highest rate of interest. But experience is accumulating that remoteness between ownership and operation is an evil in the relations between men, likely or certain in the long run to set up strains and enmities which will bring to nought the financial calculation.

Ideas, knowledge, art, hospitality, travel – these are the things which should of their nature be international. But let goods be homespun whenever it is reasonably and conveniently possible; and, above all, let finance be primarily national.

A considerable degree of international specialisation is necessary in a rational world in all cases where it is dictated by wide differences of climate, natural resources, native aptitudes, level of culture and density of population. But over an increasingly wide range of industrial products, and perhaps of agricultural products also, I become doubtful whether the economic cost of national self-sufficiency is great enough to outweigh the other advantages of gradually bringing the producer and the consumer within the ambit of the same national, economic and financial organisation. Experience accumulates to prove that most modern mass-production processes can be performed in most countries and climates with almost equal efficiency. Moreover, as wealth increases, both primary and manufactured products play a smaller relative part in the national economy compared with houses, personal services and local amenities which are not the subject of international exchange; with the result that a moderate increase in the real cost of the former consequent on greater national self-sufficiency may cease to be of serious consequence when weighed in the balance against advantages of a different kind.
