"If a Martian were asked to pick the most efficient and humane economic systems on earth, it would certainly not choose the countries which rely most on markets. The United States is a stagnant economy in which real wages have been constant for more than a decade and the real income of the bottom 40 percent of the population declined. It is an inhumane society in which 11.5 percent of the population, some 32 million people, including 20 percent of all children, live in absolute poverty. It is the oldest democracy on earth but also one with the lowest voting rates among democracies and the highest per capita prison population in the world. The fastest developing countries in the world today are among those where the state pursues active industrial and trade policies; the few countries in the world in which almost no one is poor today are those in which the state has been engaged in massive social welfare and labor market policies."

“Marx may have erred in analyzing the nature of this conflict. Interests of workers and capitalists may not be irreconcilable under all circumstances, and workers may see the choice between capitalism and socialism differently depending upon the specific political and economic conditions under which they live.”

“Is “democracy,” as we understand the term today, an implementation of “self-government,” as this ideal was formulated when representative institutions were first established? The evidence is mixed.”

“Capitalism is a system in which many scarce resources are owned privately, and decisions about allocating them are a private prerogative. Democracy is a system through which people as citizens may express preferences about allocating resources that they do not privately own. Hence the perennial question of political theory and of practical politics concerns the competence of these two systems with regard to each other. Is it possible for governments to control a capitalist economy? In particular, is it possible to steer the economy against the interests and preferences of those who control productive wealth?”

“Democracy can be an equilibrium: a system of "self-government" in which the distinction between the rulers and the ruled disappears.”

“The simple answer to the question with which we began is that we do not know whether democracy fosters or hinders economic growth.”

“What makes democracies sustainable, given the context of exogenous conditions, are their institutions and performance. Democracy is sustainable when its institutional framework promotes normatively desirable and politically desired objectives, such as freedom from arbitrary violence, material security, equality, or justice, and when, in turn, these institutions are adept at handling crises that arise when such objectives are not being fulfilled.”
