The War of 1812 perhaps the least remembered of American wars because it was fought in such a left-handed slapdash manner on both sides.

After I finished the Tycoons - on post-Civil War development - I realized how much I didn't know about the first half of the century, even though there had obviously been an enormous amount of development, so I read about and thought about that for a couple of years before I decided I was ready for a book.

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've been among their critics [MBA programs]. Much of what I've seen in business schools is quite non-rigorous. Anecdotal histories are stretched to illustrate favored slogans. Evidence of their effectiveness is similarly anecdotal.

Whitney proved to be a competent manufacturer, but wasn't an original inventor to any important degree. Thomas Blanchard was a true genius: his stock making machine was the daddy of all the industrial profiling machinery, like the 1870s universal milling machine, that was the especial American contribution to machining technology. By that time, the British conceded that machinery innovation had shifted to America.

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.
