I never heard the song “The Trees” as a libertarian piece or some commentary on communism. I saw it as two groups obsessively focussed on what sent them apart and ther own personal grievances. Their differences were what was important. To the exclusion of all else.
To the point of collapse of all. For who was wielding the hatchet, ax and saw? I never saw trees as behind that.
People use those implements. Human beings who cared little about the insignificant differences of trees.
We get too focussed on what sets us aprart and who is screwing over whom. When what will bring us all down is something outside that is a danger to all.
I think that is a better metaphor for today.
