Blame the media and our higher learning centers of education.
Blame the USSR. They planted moles in the universities, media, and entertainment to spread their poisonous ideas in the 1950s. I think that they used flattery to get the useful idiots to accept and parrot their ideas. That is, the rationale for socialism makes no sense, but they told their targets that the ideas are so complex that only super smart people understand them. Thus, the useful idiots learned to parrot those ideas because they believed it made them super smart, even as they were not smart enough to perceive that the ideas are nonsense.
We are now seeing the fruits of the work the Soviets began decades ago.
