Tim Harford writes in Reason Magazine about why poor countries are poor. The short answer? A corrupt government creates corruption all the way down the line.

The corruption is not only unfair; it is also hugely wasteful. Gendarmes spend their time harassing travelers in return for modest returns. The costs are enormous. An entire police force is too busy extracting bribes to catch criminals. A four-hour trip takes five hours. Travelers take costly steps to protect themselves: carrying less money, traveling less often or at busier times of the day, bringing extra paperwork to help fend off attempts to extract bribes.

The blockades and crooked police officers comprise a particularly visible form of corruption, but there are metaphorical roadblocks throughout the Cameroonian economy. To set up a small business, an entrepreneur must spend on official fees nearly as much as the average Cameroonian makes in two years. To buy or sell property costs nearly a fifth of the property's value. To get the courts to enforce an unpaid invoice takes nearly two years, costs more than a third of the invoice's value, and requires 58 separate procedures. These ridiculous regulations are good news for the bureaucrats who enforce them. Every procedure is an opportunity to extract a bribe. The slower the standard processes, the greater the temptation to pay "speed money."

It's a long article, but very informative. I really liked how he tied all the pieces together, and how surely the rot of bad government will reach into practically every aspect of its peoples' lives.
