Why do I say the era is “post-socialist” ??

Because the ideology of socialism never fulfilled its promise.

“ . . . on crucial points they’ll keep the government on the neoliberal track . . . prioritizing private rather than public investment.”

The left keeps failing to appreciate the nuances of this simplistic way of looking at things. It can’t seem to fully comprehend the issue that “public” within the context of mass society and the modern industrial state manifests as bureaucratic Big Government social spending. The latter can do some good, just as corporate profit-oriented production can satisfy consumption desiderata to some extent, but under current conditions both tend to be institutional, impersonal, dumb, and far from satisfactory.

Socialism never understood that scale is a more important issue than “private vs. public”; never appreciated the significance of human alienation from nature. It was fully modernist and progressivist. It thought industrialism could be the basis for a classless society. It was deluded about the “historic mission of the proletariat.”

For a century it was the hope for the future. The left should move on now to a more sophisticated worldview.
