Perry Anderson said this quote

Thirty years later, his regime had accomplished its historical task. Economic development had transformed Spanish society, radical mass politics had been extinguished, and democracy was no longer hazardous for capital. So completely had the dictatorship done its work that a toothless Bourbon socialism was incapable even of restoring the republic it had overthrown. In this Spanish laboratory could be found a parabola of the future, which the Latin American dictators of the 1970s – Pinochet is the exemplary case – would repeat, architects of a political order in which electors, grateful for civic liberties finally restored, could be trusted henceforward not to tamper with the social order. Today the Spanish template has become the general formula of freedom: no longer making the world safe for democracy, but democracy safe for this world.
