@Alon perhaps. but in retrospect and in relative terms, the economy did a lot better at providing for (nearly) all, at a decent level, than now, regardless of how left movements at the time viewed things. the racial exclusion is an important point, but convergence in subsequent decades has been more downward than upward: members of previously favored groups increasingly experience the precarity of the less favored, rather than a more desirable other way around.
