This is just plain wrong, in my view. You don't learn Communism; you learn to hate life itself, instead of the terrible system in which your shitty life happens.
The impoverished Brazilian gig worker delivering food to rich people while riding a motorcycle with Bolsonaro stickers begs to differ. I see this guy all the time. He struggles to feed his family (because communists are making groceries more expensive), he wants more police brutality (against other people), he wants followers of certain religions (not his) arrested, he says he works 18 hour days and life is tough but he works hard (and you're a lazy crybaby if you don't want to do it too).
Sure, Marx explains why his life is miserable, but there's plenty of other people willing to offer misleading but more immediately compelling explanations and these are all very appealing to somebody who was born and raised immersed in anticommunist propaganda.
