From Wikipedia
In April 1977 Panthers were key supporters of the 504 Sit-ins, the longest of which was the 25-day occupation of the San Francisco Federal Building by over 120 people with disabilities. Panthers provided daily home-cooked meals in support of the protest’s eventual success, which eventually led to the Americans with Disabilities Act (ADA)thirteen years later.
Karl Marx was a big advocate of worker rights too, not a fan of child labour or dangerous workplaces.
I raise this as the The Black Panthers were a Maoist organisation, and Maoism has a big focus on community improvement (they assume Capitalists aren’t about to help you, so you have to organise politically and collectively).
