You don't have to go as far back as the French Revolution. Labor unions in the late 19th and early 20th century fought pitched battles against the exploitative billionaire equivalents of their day, and it was much easier for the rich to accept t labor's demands when they knew there was real risk of physical harm from the workers they were exploiting. If you work an 8 hour day, or your job can't subject you dangerous conditions with no recourse, thank militant unions who were willing to lay it on the line against greedy oppressors like Zuckerberg.

These days though, you got half the population rooting for the billionaires. They'll tell people if they don't like their working conditions or pay, just find a new job.
