I've been in China enough to know that you shouldn't opine on it unless you speak Chinese and have lived there for twenty years. I wasn't pretending to be a China expert in that final chapter. I was just pointing, first to the parallels between Chinese behavior toward us and ours toward GB when we were at the same stage of development, and secondly to how much harder their development path is than ours was.

I would speculate that a critical mass of the population has to internalize a middle class outlook first. International aid experience has demonstrated many times that just building railroads doesn't get you there. You need people ready to sue them.

Credit is the air that financial markets breathe, and when the air is poisoned, there's no place to hide.

No specific technology. My guess is that it was the instinct always to go to maximum scale. Great Britain kept much more of a small shop mindset well into the twentieth century, for instance.

I think it was the occasion of the final psychological break with Great Britain, in a way that had clearly not happened to that date, especially in New England and to som degree in the South.

The paradigm of the development of natural resource-based industry - meatpacking, lard, timber, iron and coal, grain. Cincinnati's lard processing plants looked a lot like JDR's oil refineries thirty years later.

It may not be replicable: One of the hardest transition that a developing country can make is the transition to middle-class status. Governments have to let go, people start insisting on following their own lights, etc.
