I just started reading Amartya Sen's 1999 book
Development as Freedom.
Sen's book argues that, rather than measuring development in terms of GNP or income, it should be measured in terms of freedoms. He gives examples of where GNP/Income disguise other problems. For example, black men in Harlem have much shorter life expectancies than men in many African nations even though black men in Harlem are much wealthier than in those nations where they are outlived. How can you be better off because you're wealthier but enjoy half as many years on earth that other people enjoy?
Sen talks about democratic freedoms and how they contribute to overall freedom and well-being, regardless of whether they produce a nation with a high GNP and high incomes. (He says that a country must have both democratic processes and and outcomes for "democracy" to produce good results for citizens).
Sen discusses Singapore in this context. Apparently some economists use Singapore as an example of how a nation doesn't need freedoms so long as it provides high incomes for its citizens. Sen says that, in fact, there isn't any evidence that authoritarian politics help economic growth (and that empirical evidence strongly suggests that economic growth is more a matter of a friendler economic climate than of a harsher political system).
Friedman's article in the New York Times recently is generally an argument that an authoritarian government is capable of taking good care of citizens during crises like the one in New Orleadns. However, I think it's important to keep in mind that nothing about authoritarian governments, according to Sen, inherently provides better lives for its citizens. In fact, according to the book The Health of Nations, which is the book which, because it cites Sen, inspired me to read Development and Freedom, there's a strong implication that it's the fact that everybody is in the same boat and that there aren't huge disparities in wealth, that encourages a society to look after everyone and not leave the poor to fend for themselves (and might be a better explanation for at least why China and Cuba are able to evacuate 100s of thousands of citizens in situations like the one in N.O.).
Incidently, Sen points out that no country with a democracy, as of 1999 (when the book was published), ever suffered from a famine. The nations today at the top of the famine league are North Korea and Sudan -- two countries with dictatorships. In fact, countries that suffered famines during colonial years then did not have famines as soon as they switched to democracies. One explanation, according to Sen, is because democracies have to respond to the people. Also, dictators don't know how the people live. They never suffer the poverty of the rest of the nation when times are lean.
Here's Friedman's article:
