> removing development restrictions in booming cities, unleashing an epic (or Chinese-level) building boom Which would be interesting because it is debatable whether we have the resources for that. On one hand, we have people like Tim Worstall of Forbes claiming that we will never run out of metals that would be used in a building boom, because innovation reduces and replaces use of existing metals, e.g. modern day pennies use steel and a copper coating: http://www.forbes.com/sites/timworstall/2011/10/15/when-are-... Although, I think Tim takes a lot of liberty with his assessments, like his recent wild speculation that humanity could never populate another star system because it would take too many people to preserve our culture: http://www.forbes.com/sites/timworstall/2014/04/07/perhaps-c... On the other hand, in http://en.wikipedia.org/wiki/Iron_ore#Available_iron_ore_res... it states that Lester Brown of the Worldwatch Institute has suggested iron ore could run out within 64 years based on an extremely conservative extrapolation of 2% growth per year, and so if there were a boom, innovation to replace use of iron ore as a structural component would be required. |
