Societies, whether traditional or modern, experience tension between spontaneity (individual freedom) and control (regulation). Consequently, economies as a subsystem of society experience it too. More specifically, they experience a tension between economic individualism and economic collectivism, which in modern economies revolves around the role of the state in the economy. Since the collapse of communism, this tension has manifested itself not as a tension between market capitalism and command socialism but as a tension between the free market and the interventionist variants of market capitalism. Although currently economic and political liberalization is in evidence worldwide, not only in post-communist societies, its outcome remains uncertain.
