The leadership of the Bolsheviks were all pretty much at least middle class origins. They used the plight of the 'working class' and 'peasants' to manipulate and gain power, just as our modern-day Bolsheviks use the plight of black people.
The Bolshevik’s also spent decades developing relationships with the “working class”. They worked on if not led in worker’s rights and unionization which of course the would betray later once in power. The current Antifa if they walked into a union hall they would be laughed at, scorned, their butts kicked if they got too annoying. Their only safe haven is a college campus. That’s why their ranks had to be stiffened with criminal jail releases (Due to COVID-19 !).
