CONSERVATISM IS ALWAYS RIGHT IN THE LONG RUN...:

The United States is an example of a situation that is favorable to a common currency. Though composed of fifty states, its residents overwhelmingly speak the same language, listen to the same television programs, see the same movies, can and do move freely from one part of the country to another; goods and capital move freely from state to state; wages and prices are moderately flexible; and the national government raises in taxes and spends roughly twice as much as state and local governments. Fiscal policies differ from state to state, but the differences are minor compared to the common national policy.

Unexpected shocks may well affect one part of the United States more than others -- as, for example, the Middle East embargo on oil did in the 1970s, creating an increased demand for labor and boom conditions in some states, such as Texas, and unemployment and depressed conditions in others, such as the oil-importing states of the industrial Midwest. The different short-run effects were soon mediated by movements of people and goods, by offsetting financial flows from the national to the state and local governments, and by adjustments in prices and wages.

By contrast, Europe's common market exemplifies a situation that is unfavorable to a common currency. It is composed of separate nations, whose residents speak different languages, have different customs, and have far greater loyalty and attachment to their own country than to the common market or to the idea of "Europe." Despite being a free trade area, goods move less freely than in the United States, and so does capital.

The European Commission based in Brussels, indeed, spends a small fraction of the total spent by governments in the member countries. They, not the European Union's bureaucracies, are the important political entities. Moreover, regulation of industrial and employment practices is more extensive than in the United States, and differs far more from country to country than from American state to American state. As a result, wages and prices in Europe are more rigid, and labor less mobile. In those circumstances, flexible exchange rates provide an extremely useful adjustment mechanism.
