Does this seem "anti-mustachian" to you as well, and if so, what should we do about that?
I share this concern to some degree.
I come from a community that is...extremelyaboutsharing, so hanging in Mustache Land involved an intense shift in my personal culture, as well as in how easily I can relate with my longer-time community. In the latter, ANY money that came in was immediately distributed amongst everyone. Not as a result of decree, politics, etc, but because this is what was natural for us. Each of us knew hardship, thus empathized with feelings around lack and feelings around relief, and we responded to those. That culture had pros and cons, as all ways do (I wrote a book and talk about this more in there).
Many Mustachians do ponder (and act on) how to share or give in effective ways, but it's still super weird for me to be hoarding money for my will. I continue to feel conflicted about it. My body feels compelled to distribute it all. I don't because I can't stand the thought of returning to my earlier life.
I guess the difference between cultures like Junger describes and our current one is that in the former, ones material needs will be met while in ours, they won't necessarily. Of course, today, some people attempt to recreate the intentional community life (see ic.org). My psyche is a huge fan of the concept, but my immersions in eight of these left me opting out and being careful to preserve Independence Funds. I'm sad about that though.
