We have not had real capitalism in this country since the Gilded Age, when the dollar was backed by gold. Fiat currency and Keynesian economics sparked the mess that were are in today.
Yeah, capitalism globally fell to the mixed economy throughout the developed world, to the point that most modern references to “capitalism” refer to the mixed economy, not the original system named “capitalism”, because while people may not have been sold on the prescriptions of more radical alternatives like Communism, they broadly weren't satisfied with capitalism, either.
