Let’s agree that if you’re one of ‘the 1 per cent’ you’re objectively rich. So far, so uncontroversial. But let’s further agree, at least for now, that we’re all human, and therefore our richness should be determined on a global scale (suitably adjusted for relative costs of living). Still, I hope, uncontroversial. Yet this is at odds with what as-near-as-makes-no-difference everybody believes. Because believing it makes you undeniably rich, but robs you of your excuses for not doing something sufficiently brilliant on the back of it.
