Oh, I'm not saying the projects are without any purpose or benefit. I'm saying the decision to do them as "large scale projects" usually reveals thinking and reaction to problems of a modernity focused around centralization.
The comparison I was drawing is not one of Three Gorges dam or no Power, or Notre Dame and no churches. But is Three Gorges Dam a decision made as a result of the problems of making "China?" Is Notre Dame better than dozens or perhaps hundreds of humble churches throughout France?
I'd say that there is something qualitative in Notre Dame which makes it more than the sum of a hundred or a thousand churches, but I take your point that it's a question of allocating resources - it's not immediately obvious that a Notre Dame isn't worth (almost lapsing into Civ terms) an Oxford University or a thousand hospitals. I also take your point that many projects are made with the intention of benefiting the state - my point, though, was that despite that they're still useful and helpful to the people living in the state. We may safely assume that Three Gorges Dam is a more efficient way of generating power than the same amount of money in little dams, otherwise the Chinese would have built a massive dam network.
