Maybe it's because I'm a redneck who is ideologically derived from Jeffersonian democracy rather than Marxism but I severely doubt any traditional Marxist structured power would work as a counter. I think that the capitalist powers basically got lucky with the World Wars and the great depression since they basically worked to pave over a lot of the woes of industrialization that were starting to hit around 1910, but it turns out killing an entire generation on the western front is great for reducing unemployment in the future, then the depression cleaned up a lot of chaff and made businesses a lot less reckless, and WW2 leveled much of Europes industrial base which while it sucked did create a lot of work and allowed them to rebuild from first basics.

What I think were seeing is the inevitable collapse of a globally financialized economy running into actual baseline economic issues that it simply can't address due to its financialized structure. Frankly even if the Soviets had survived as a viable counter it at most wouldve been delayed because the seeds of the crop we witnessed were planted with the fallout of Nixon and fucking Reagan.

Also just a bit of context but derivatives of Jeffersonian democracy generally have much less focus on the whole Yeoman farmer thing and shift it instead into localized economic structures, basically corporations bad local businesses and co-ops good.
