I'm not arguing that this is reality, I'm just saying our attitude is such that anything is achievable. Maybe that makes us naive, but it also makes us much more likely to take a big risk for a big payoff.
I confess I don't know France well enough to add to your views on it's economic attitudes, but I do know the US well enough to say what I just said. I think the point of the article is that since we are not taught to fear capitalism, we are more likely to do stupid things that sometimes actually pay off, and the pay off is generally worth it for society, if not for the individuals that failed en route.
And I think France was the #1 power in the world briefly... the Napoleonic Era. Either way, it has been one of the top powers for quite a while. I, as an American, am still envious of your prowess in Nuclear Energy.
