David Wessel in the Wall Street Journal reports on economist Alan Krueger's controversial claims about what breeds terrorism:
"As a group, terrorists are better educated and from wealthier families than the typical person in the same age group in the societies from which they originate," Mr. Krueger said at the London School of Economics last year in a lecture soon to be published as a book, "What Makes a Terrorist?"
"There is no evidence of a general tendency for impoverished or uneducated people to be more likely to support terrorism or join terrorist organizations than their higher-income, better-educated countrymen," he said. The Sept. 11 attackers were relatively well-off men from a rich country, Saudi Arabia.
As it happens, this analysis runs contra to many others:
Less than a year after the Sept. 11, 2001, attacks, President Bush said, "We fight against poverty because hope is an answer to terror." A couple of months later, his wife, Laura, said, "Educated children are much more likely to embrace the values that defeat terror." Former World Bank President James Wolfensohn has argued, "The war on terrorism will not be won until we have come to grips with the problem of poverty, and thus the sources of discontent."
