Why do communes always fail?

Why do communes always fail?

            I live in an area in east Tennessee full of failed communes, and some of the latest efforts, too.
 

 People are selfish, period. Some more than others. 

 I even have one identifiable mass grave  around here, too. It was bulldozed over almost ten years ago, which has always disturbed me. The mass grave is still there, but the mound and flat creek stone marker is gone, often  like our own memories when we die. Now I have GPS'd it mostly because I wanted to.  

Many of these failed communes with their own mass graves often had  political associations, too. Ideas like Bohemian and English younger brothers and Beatnik and later Hippie come to my mind in 2013.

This idea has always amplified itself when people get cold and hungry, and then try choose another way that gives them more hope. Hope does spring eternal when idealism and sex get mixed together, too.

 After all,  most communes still often have enough lazy people who try mooch off of the hard working people, who eventually get rid their fellow types, and the then whole thing eventually dissolves as people then move on, or die in place. In other words, the commune fails naturally. 

Drugs and alcohol often exacerbate the situation, too.

In Marine Corps talk, I would suggest the classical line...good initiative and poor judgment.

I almost became one of them before I chose my own path, by the way. I did truly make my own choice now over a half-century ago. Growing corn in the desert outside of Taos  and living naked in a cave was just not that appealing, to me. Especially compared to my other choices, by the way.

Even "friends with benefits" only goes so far. After all it is about "us" and not "I" for things to sort out for the best, like our children's futures.

My now old person line is even more primitive...nobody wants to be cold and hungry when they think there is a better way to go...especially if their kids are involved.
