Surfing YouTube, I came across an interview of Ezra Klein by Stephen Colbert. He was promoting a new book called Abundance, basically arguing that scarcity is politically-manufactured by “both sides,” and that if we get our political act together, everybody can have more. Planetary limits need not apply. I’ve often been impressed by Klein’s sharp insights on politics, yet can’t reconcile how someone so smart misses the big-picture perspectives that grab my attention.
