> I'm also somewhat doubtful of cost-of-labour explanations. Wouldn't it be rational for some organizations to pay a lot more to get people to work longer hours if that's all that's going on? (It would almost certainly be cheaper to do that than to have the project take twice as long in total.) And why did many of the instances enumerated on the page happen in relatively high cost (for the time) locations, like New York, DC, and San Francisco, rather than in cheaper places? As far as I can tell, for a lot of transit projects in the US, at least, the capital isn't there up-front to just pay more to parallelize things. The money is being raised by a long-duration tax so it comes in incrementally. And then there's a second closely related factor: do we have the production capacity to switch from a five-year-project-horizon to a one-year one even if we wanted to spend the money faster? It seems like it feeds itself, when it comes to cities and infrastructure: - huge early growth spurs a big demand, construction industry spins up around it (this, I think, answers the "why did stuff happen in high-cost areas" question - high demand is what causes high cost, so in an area where nobody is demanding infrastructure, there's gonna be a lot less reason to build it) - a lot of stuff, once built, will last decades or longer, and would be extra-hard and expensive to replace. so once demand starts to be met, and growth starts to slow, the construction industry gets less and less business, so it shrinks - this is a limiting factor on new projects, but they're also seen as less urgent than the initial stuff (road widening is less critical than creating a road where there was none, say), so the slower pace is accepted. - red tape also starts to develop, since in a new-frontier situation there are fewer entrenched powers to create regulations to protect things (whether or not those regulations are net-beneficial!) That's my current pet theory, anyway: It's not that we've deteriorated, it's more that priorities, effort, and industry have shifted. There are a LOT of other things that happen far faster now than they did 30 years ago in 1992, after all; and unbelievably faster than they did when the Empire State Building was constructed. Sometimes it's harder to repair a body than to make a new human in the first place, if you will ;) |
