I have no clue how people who don't understand Marxian political economy can understand things like the huge dot-com bubble in the late 1990s, and then the crash. Or the (sub-prime) real estate bubble. Or how the finance sector is growing, in GDP percentage wise and in power, relative to the economy which produces real commodities.

Then again, according to polls (and my experience), the majority of Americans believe "every word of the Bible is literally accurate", and that "the Virgin birth, the angelic proclamation to the shepherds, the Star of Bethlehem, and the Wise Men from the East" are "historically accurate". Over 70% believe in "God, Heaven, the resurrection of Christ, survival of the soul after death, miracles, the virgin birth, the devil and hell". If blindness to the way the world really works is so overwhelming with these fantasies, expecting people to understand how wealthy people discretely work the economic system is way, way beyond most people.
