I think there's a lot of questions about power and responsibility we need to have.
Like is some of the bunker mentality coming from a feeling of lack of power and wishing to have it over others?
I tend to see power as a responsibility, and I absolutely want to share it with others to spread the load.
I grew up with a Father who shared food with my friends at the drop of a hat. I also grew up around folks who donated their baby clothes to new parents. It's why mutual aid makes sense to me.
