The Dutch call their collectivist mentality and way of politics-by-consensus the “polder model,” after the areas of low land systematically reclaimed from the sea. “People think of the polder model as a romantic idea” and assume its origins are more myth than fact, Mak told me. “But if you look at records of the Middle Ages, you see it was a real thing. Everyone had to deal with water. With a polder, the big problem is pumping the water. But in most cases your land lies in the middle of the country, so where are you going to pump it? To someone else’s land. And then they have to do the same thing, and their neighbor does, too. So what you see in the records are these extraordinarily complicated deals. All of this had to be done together.”

Obviously this history of collective action in response to the sea does not exist in the States, and any adaptation of the Dutch experience to the US flood control system ought to be done with an awareness of how differing historical experiences inform present conditions.

(Thanks for reminding me where I had read that, Stephen).
