A brief summary of Walter Russell Mead's view of the world. He links to a Fukayama essay, The Two Europes. One quote on the topic of political clientilism:
Clientelism occurs when political parties use public resources, and particularly government offices, as a means of rewarding political supporters. Politicians provide not programmatic public policies, but individual benefits like a job in the post office, an intervention on behalf of a relative in trouble with the government, or sometimes an outright payment of money or goods.
In my view, clientelism should be distinguished from corruption proper because of the relationship of reciprocity that exists between politicians and voters. There is a real degree of accountability in a clientelistic system: the politician has to give something back to supporters if he or she is to stay in power, even if that is a purely private benefit.
