Discipline applied by the bourgeoisie is ultimately just coerced self-discipline. We see a natural instinct to instill it in school children, and part of the purpose of grading a student is to rate them on a rubric of self-discipline (under capitalism). By the time most of us are finished with school, we've developed our own inner capitalist that tells us how to behave.

And that's taxing! Having to moderate your impuse to tell a karen to fuck off, or to leave work early exhausts us, and makes it that much more difficult to self-regulate in other areas of our lives. Constant advertisements throughout the day take advantage of this as well.

I hear people call American Leftists lazy all the time and it drives me nuts because we're mostly working class, and the US working class works more hours than anyone not specifically being colonized.

We're not lazy, we're tired, by design.

That said, if our forebears from the 1900s could find time to agitate during 16 hour workdays, we can too.
