Because life sucked in the country, and the Marxist Allende (elected in 1970) proceeded to further destroy the economy until stopped by Pinochet in 1973. A series of reforms — commonly known today as "Miracle of Chile" — were necessary. The upswing in the blue line, that outperforms the orange line so convincingly today started in 1984 — with a minor hiccup in 1988, when Pinochet stepped down after losing a referendum.
