KABUL, Afghanistan  When it comes to governing this violent, fractious land, everything, it seems, has its price.

Want to be a provincial police chief? It will cost you $100,000.

Want to drive a convoy of trucks loaded with fuel across the country? Be prepared to pay $6,000 per truck, so the police will not tip off the Taliban.

Need to settle a lawsuit over the ownership of your house? About $25,000, depending on the judge.

“It is very shameful, but probably I will pay the bribe,” Mohammed Naim, a young English teacher, said as he stood in front of the Secondary Courthouse in Kabul. His brother had been arrested a week before, and the police were demanding $4,000 for his release. “Everything is possible in this country now. Everything.”

Kept afloat by billions of dollars in American and other foreign aid, the government of Afghanistan is shot through with corruption and graft. From the lowliest traffic policeman to the family of President Hamid Karzai himself, the state built on the ruins of the Taliban government seven years ago now often seems to exist for little more than the enrichment of those who run it.
