Privation alone isn't enough to awaken political consciousness, though. That's why you need a vanguard party, and that's why political education is such a big part of socialist praxis. Like obviously Bernie isn't in any way a Marxist-Leninist or even a socialist, but his messaging was closer to the truth than the ruling class propaganda that tells poor people the reason they're poor is because of capital gains taxes/welfare queens/business regulations/immigrants.
