" Perhaps it had nothing to do with the Taliban and everything to do with perverse incentives created by rapid and uneven development in a tribal society whose economic, social, and agricultural systems have been wrecked by decades of war. No external aid is neutral: a sudden influx of foreign assistance creates a contracting bonanza, benefiting some at others’ expense, and in turn provoking conflict. Likewise, it creates spoils over which local power brokers fight for personal gain, to the detriment of the wider community, and can contribute to a sense of entitlement on the part of locals. Access to foreigners, who have lots of money and firepower but little time or inclination to gain an understanding of local dynamics, can give district power brokers incredibly lucrative opportunities for corruption. A tsunami of illicit cash washes over the society, provoking abuse, raising expectations but then disappointing them, and empowering local armed groups, who pose as clean and incorruptible, defenders of the disenfranchised, at least till they themselves gain access to sources of corruption.14 "
