The bureaucratization inherent in Communist regimes was also responsible for the economic failures that either contributed to their downfall or else compelled them to abandon Communism in all but name. The nationalization of productive assets led to the transfer of their management to officials who had neither the competence nor the motivation to operate them efficiently. The inevitable result was declining productivity. Furthermore, the rigidity inherent in centralized management made Communist economies unresponsive to technological innovation, which explains why the Soviet Union, despite its high level of science, missed out on some of the most important technological discoveries of recent times. As Friedrich Hayek has pointed out, only the free market has the ability to sense and respond to shifts in the economy. And only the prospect of enrichment motivates people to exert themselves beyond their immediate needs. Under Communism, effective incentives were lacking: indeed, diligence at work was punished, in that meeting one’s productivity quotas resulted in these quotas being raised.
