I'm starting to have some issues with socialism. I can't find a way in which it... I guess works. Even the Democratic-Socialist countries which still have freedom and free information seem to fall behind in brute technological progress and GDP.
Let's restructure this observation so that it takes the form of an analogy.
"I'm starting to have some issues with generalism. I can't find a way in which it.. I guess works. Even the neo-generalist animals which still have vestiges of specialist features seem to fall behind in brute efficiency and environmental adaptation."
EG, when you have a group that specializes almost exclusively on worship of "the free market", and "innovative cost savings", with emphasis on wealth generation--- vs groups that are more focused on overall health of a society instead of how much money it can make, and how quickly/efficiently, it makes no sense to complain that the latter does not perform with the same caliber of performance, in the specialized metrics of the specialized former.
For many of the same reasons that "Pure generalism" in an organism is untenable, "pure socialism" is also untenable. The ideal is some degree of specialization, with enough generalization to be able to survive an upset of the status quo, without being either so generalized that you are weighed down with unneeded (and expensive) survival kit in environments where it is not needed--- while also not being so hyperspecialized that a 1 degree change in temperature results in species wide extinction.
Similar story with capitalism vs socialism. Pure capitalism is so hyperspecialized on economic growth that it cannot cope with the reality that it is unsustainable/will cause massive planetary biosphere destruction along with massive wealth disparities that destroy the population.
Pure socialism is so generalized in how it idealizes the ability to selflessly redistribute resources, and optimistic in how tragedy of the commons will not occur that cannot sustain itself in the face of more specialized systems that are vastly more efficient.
The perfect mix is somewhere in the middle, on both things.
