More May Day reading material. If Piketty is not to your taste, try Atlas Shrugged, the 1,000 page plus doorstoper by Ayan Rand, muse to Alan Greenspan, former US Federal Reserve chairman. It's fiction, of course, but as a paean to unbridled capitalism, it's an unsurpassable romp. It's about captains of industry who withdraw their labour and seek refuge in their version of Shangri-La, wrecking the US economy - deprived of their ingenuity, their pursuit of profit and self-interest. The book features a speech by the hero, John Galt, that goes on for 60 pages setting out Rand's argument for capitalism. Apparently those pages took Rand two years to write.
