Australia is attractive for its open spaces, whereas the American frontier is now closed; Holland seems a safer bet for one’s money than Italy where social unrest and economic uncertainty cloud the future; holidays in Switzerland may be expensive, but one is less likely to get involved in a revolution or civil war than around the Mediterranean Sea. The end of the average means that much more attention will have to be given to differences, to regional or structural policies for example in addition to general economic policy, and that the internal flexibility of societies matters more than their capacity to expand. Britain, once the leader of economic development, has been out of step with the times more recently. There is more to socialism than lagging gross national products and closed borders of course, and the differences between socialist countries are as great as those between Britain and Germany or France or Sweden.
