From my column today:

The sad truth about Haiti isn’t simply that it is poor, but that it has a poverty culture. Yes, it has had awful luck. Absolutely, it has been exploited, abused, and betrayed ever since its days as a slave colony. So, if it alleviates Western guilt to say that Haiti’s poverty stems entirely from a legacy of racism and colonialism, fine. But Haiti has been independent and the poorest country in the hemisphere for a long time.
Even if blame lies everywhere except among the victims themselves, it doesn’t change the fact that Haiti will never get out of grinding poverty until it abandons much of its culture.
When Haitians leave Haiti for the U.S. they get richer almost overnight. This isn’t simply because wages are higher here or welfare payments more generous. Coming to America is a cultural leap of faith, physically and psychologically. Arnold Kling and Nick Schulz note in their phenomenal new book, From Poverty to Prosperity, that low-skilled Mexican laborers become 10 to 20 times more productive simply by crossing the border into the United States. William Lewis, former director of the McKinsey Global Institute, found that illiterate, non-English-speaking Mexican agricultural laborers in the U.S. were four times more productive than the same sorts of laborers in Brazil.
Why? Because American culture not only expects hard work, but teaches the unskilled how to work hard.
