Harvard professor and former chief economist at the IMF Kenneth Rogoff addresses five [via Greg Mankiw]:

First, even the leading capitalist economies have failed to price public goods such as clean air and water effectively. The failure of efforts to conclude a new global climate-change agreement is symptomatic of the paralysis.

Second, along with great wealth, capitalism has produced extraordinary levels of inequality. The growing gap is partly a simple byproduct of innovation and entrepreneurship. People do not complain about Steve Jobs’s success; his contributions are obvious. But this is not always the case: great wealth enables groups and individuals to buy political power and influence, which in turn helps to generate even more wealth. Only a few countries – Sweden, for example – have been able to curtail this vicious circle without causing growth to collapse.

A third problem is the provision and distribution of medical care, a market that fails to satisfy several of the basic requirements necessary for the price mechanism to produce economic efficiency, beginning with the difficulty that consumers have in assessing the quality of their treatment.

The problem will only get worse: health-care costs as a proportion of income are sure to rise as societies get richer and older, possibly exceeding 30% of GDP within a few decades. In health care, perhaps more than in any other market, many countries are struggling with the moral dilemma of how to maintain incentives to produce and consume efficiently without producing unacceptably large disparities in access to care.

It is ironic that modern capitalist societies engage in public campaigns to urge individuals to be more attentive to their health, while fostering an economic ecosystem that seduces many consumers into an extremely unhealthy diet. According to the United States Centers for Disease Control, 34% of Americans are obese. Clearly, conventionally measured economic growth – which implies higher consumption – cannot be an end in itself.

Fourth, today’s capitalist systems vastly undervalue the welfare of unborn generations. For most of the era since the Industrial Revolution, this has not mattered, as the continuing boon of technological advance has trumped short-sighted policies. By and large, each generation has found itself significantly better off than the last. But, with the world’s population surging above seven billion, and harbingers of resource constraints becoming ever more apparent, there is no guarantee that this trajectory can be maintained.

Financial crises are of course a fifth problem, perhaps the one that has provoked the most soul-searching of late. In the world of finance, continual technological innovation has not conspicuously reduced risks, and might well have magnified them.

This is certainly a good supplement to the concerns I laid out a few days ago.  I think number four — the idea that future generations might not see the sort of welfare gains that characterized the 20th century’s massive leap into modernity — is particularly underappreciated.  I wonder if this leap has been completed and we’re now at the point where societal advance will be significantly overshadowed by our flaws becoming more and more prominent.  After all, every individual concern can be lumped into a very basic one: the sustainability of our system.  There’s no doubt that letting our basic flaws go unaddressed — or simply insufficiently addressed — may call this seemingly taken-for-granted assumption into doubt.
