A bit more specifics, to follow up:
GDP growth rate, for instance, in the US doesn't have a significant inflection point around Reaganomics and its increases in deficit spending + "pro-growth" lowering of tax rates on the wealthy. We've never really gone away from that philosophy despite not seeing increases in growth + seeing a LOT of increases in inequality and the elites thriving while everyone else gets squeezed.
Perhaps "growth" is driven primarily by cultural and technological factors (especially the latter!) and inequality is driven primarily by whether or not a population has the balls to say "even if economies of scale suggest that wealth will concentrate in big mega-players, we want to fight that"? And the US had the will to do that 90 years ago, but was successfully brainwashed into giving up on it *despite the 50s in particular being still seen even by those on the right as a "golden age" of both growth and "everyman" quality of life?
If the PC revolution had started seven years earlier and the Iranian revolution had occurred seven years later how would our views of Carter vs Reagan (or some other Republican in 1984 instead) change? But which of those things did they actually cause personally?
