As to Soviet median income growth, I infer that from two things:
Soviet GNP grew at 1.8% a year in both the 1975-1980 and 1980-1985 periods, according to CIA numbers. Population was growing at about 0.95% a year, so that works out to 0.85% growth per year in average income.
Economic inequality decline in the Soviet Union in both the late 1970s and early 1980s (see here: Ayn Stalin: Soviet Inequalities In 1929-1954 and M. Alexeev and C. Gaddy, 1992, “Income distribution in the USSR in the 1990s”) so the median had to be increasing at least as fast as the mean, I…e 0.85% per year was the minimum rate of increase.
This of course is an eccentric comparison, the archival data indicate very clearly the soviet economy falling into deeper and deeper dysfunction, the post soviet collapse being the removal of a masque.
he is a Soviet apologist who likes to pretend the soviet system operated well.
Which is the driving force among a number of disaffected people supporting Trump’s demagoguery.
Your point only indicates that the U.S. has been lucky enough to avoid the phenomenon prior to 2016, not that the U.S. cannot fall prey to the same forces. We have already dallied with such errors as early as 1798 and 1917/1918, (and danced along its edge throughout the nasty silliness of the Red Scare).
