He comes from a philosophy background, and I’m not really interested in his weird Kant vs Hegel diversion, but for his attempt to synthesize fiat money & socialism, which is what I suspect China has already achieved. China is allowing some limited private ownership of the means of production, and they have sovereign fiat money.
As far as I know (which isn’t all that much) fiat money/Keynesianism/MMT hadn’t yet been developed when Marx was writing on capital. I have a suspicion that these innovations may have “resolved” some of capitalism’s internal contradictions, such that it might never collapse on its own. For instance, did Marx consider that the State might just print money to bail out the too-big-to-fail monopolies indefinitely, or that the State might prop the monopolies up by becoming their buyer of last resort? American capitalism seems to have entered uncharted territory.
