Nope. Too much futurology, although, to be fair, I haven't actually read Wealth and Poverty, only his bit pieces.
As an aside, I was re-reading Revolt of the Masses in an Irish pub in Madrid, just after the 9/11 attacks, and some Irish putz came up to me and said that if I really wanted to understand why Bin Laden hated us (not that that is what I was attempting to do), I should read some Noam Chomsky. I decided to leave rather than smash my Guiness over his head.
The great thing about Ortega y Gasset is his view on "The Barbarism of Specialization," which made me realize that I wasn't a total loser for leaving grad school with only a master's.
OK -- so that explains it.
Gilder has turned into a bit of a loony-tune, in my mind. But Wealth and Poverty was written back in the 1970s and was considered the pre-eminent treatise on supply-side economics at the time. Gilder released a subsequent edition in the 1980s, after his original theories had been utterly vindicated during the Reagan years.
I would strongly recommend it -- it reads as a splendid mix of economics, philosophy, and politics.
In fact, I now have to buy myself another copy of it -- I lent mine to my company's financial advisor, and he's never given it back. LOL.
