Up to a point, GDP does tell us important facts about people's lives, livelihoods and aspirations. Living on a dollar a day is miserable no matter how you look at it. Choking on economic growth, of course, is equally bad.

I spoke at length with DeChristopher about hacking the Democratic party, arcane but vulnerable processes like elections and auctions, why Americans really should spend more time in prison, and other tragicomic matters of consequence. Read up, plug in, turn out.

Hong Kong has surpassed New York City in several ways, including number of high-rises, population density, and modern, highly-efficient mass transit. Yet there is one area in which Hong Kong is lagging far behind -- cutting the energy use and carbon emissions from buildings.
