[...] But we should recognize that the Soviet Union was not equivalent to socialism and thereby somehow directly analogous to capitalism. It was something more particular and of a different order.

This is so whether we treat capitalism as a set of practices that can be undertaken by capitalists anywhere, or as an economic system that knits together enterprises, markets, investments, and labor throughout the world. Capitalism is a historical formation, grounded, as Michael Mann would say, in a set of power networks. It has existed for the last 400 years primarily in the form of the modern world-system that Immanuel Wallerstein has analyzed. This is a hierarchical and unequally integrated organization in which the primary units are nation-states and economic actors are crucially dependent on relations with and conditions provided by political power.

To be sure, the idea of a nation-state is in a sense aspirational; the suturing of sociocultural identity to governmental institutions is never perfect; economic integration can itself advance national integration and certainly economic actors also influence government. Yet even if partially a fiction, the nation-state is a crucial formal unit for participation in global affairs, reproduced in political isomorphism. Most international organizations are literally that—structured by nationally organized participation. And states organized in this way provide crucial underpinnings to capitalism. They provide the legal and monetary bases for both firms and markets. They manage, or provide settings for the management of interdependence among different firms, industries, and sectors. By organizing structures of cultural and social belonging, however imperfectly, and sometimes by regulating markets, they organize workforces, consumer markets, and trust. The term "nation-state* may be only shorthand for "efforts to organize politics and sociocultural belonging in terms of nation-states", but the era of capitalism and the era of nation-states have been one and the same. There is no "rea" capitalism, no matter how global, that isn't conditioned by this political-economic and sociocultural organization. The import of this is that existing capitalist prosperity and sustainability depend on nation-states and institutional affordances they have provided. These must be renewed or replaced. Yet for forty years the OECD countries have turned away from this task. Instead they have hollowed out the "welfare state" institutions of the past, reducing costs and pursuing immediate competitiveneas but neglecting the long-term well-being and security of their population and the collective investment that enables future economic participation.
