David Rolfe Graeber (/ˈɡreɪbər/; February 12, 1961 – September 2, 2020) was an American anthropologist and anarchist activist. His influential work in economic anthropology, particularly his books Debt: The First 5,000 Years (2011), Bullshit Jobs (2018), and The Dawn of Everything (2021), and his leading role in the Occupy movement, earned him recognition as one of the foremost anthropologists and left-wing thinkers of his time.
This just goes to show that theory heavy anarchists and other leftists need to bring that theory to the blue collar working class who works the water treatment plants and other infrastructure. A lot of them are union jobs it shouldn’t be too hard to get people down with anarchist concepts if explained in a way that’s not theory heavy.
Which means you are hoping they are motivated by altruism and I don't believe everyone is.
People can be motivated to pitch in because they rely on everyone else to pitch in. For some, that's growing food, and for others, its keeping the plumbing running.
I refer you back to the previous comment
You can believe what you want about altruism. Mutual aid is not necessarily altruism.
It is when one job involves life risking work and the other does not.
