Rostow hinted at his uncertainty of what might lie over that horizon, briefly acknowledging ‘the question beyond, where history offers us only fragments: what to do when the increase in real income itself loses its charm?’4 But he did not follow his own questioning through, and for understandable reasons: it was 1960 — the year of John F. Kennedy’s election bid on a promise of 5 percent growth — and for Rostow, a soon-to-be presidential adviser, it was wise to focus on keeping that plane in the sky, not on pondering when and how it would ever land.
