That's just one, very plausible, possible back story. (https://en.wiktionary.org/wiki/clogs_to_clogs_in_three_generations https://en.wiktionary.org/wiki/clogs_to_clogs_in_three_gener...) But some wealth is effectively a windfall. Tim Harford's point is that we aren't inclined to think about opportunity cost. It doesn't, in fact, come naturally. A life of privilege has opportunity costs too: it can be really hard for someone "well born" to acquire certain competences. And an (elective?) nerd's opportunity cost is all those things that jocks enjoy. (A ridiculous example, sorry!)
