Traveling the Massachusetts Turpike, looking at traffic and rusty bridges, brought this to mind. The bicycle effct was recently described by Paul Krugman. But he didn't say this... Unless it can keep destroying the planet at accelerating rate, capitalism falls over.
So I wouldn't look to a capitalist model, as neoliberalism always does, as a way to make anything better, as was claimed by some in a recent debate I participated in regarding how to make education better. All the assumptions of classical economics, and all of its successors, are fundamentally wrong because they take too narrow a focus, among other things.
What is the correct way to finance infraatructure and everything else? From each according to their ability of course.
