Lyric discussion by Girotto 

To be fair, I don't think it's about the social disparity between the Oaks and the Maples. It's simply a critique to the modern day world society. Biologically speaking, oaks and maples in the wild have adapted to their own niches and can happily live without interfering with each other. In this case however, trees become a metaphor of human society, where individuals always want more, despite they can live peacefully in their current situation. The end result of this competitiveness for light is that both parties are equally harmed and none of the two actually gains anything from the upheavel. Just my interpretation.

It also speaks wonders as to the folly of trying to legislate income equality. The oaks were all cut to the height of the maples, causing them harm. But then, not all maples are the same height either? Since they must be "kept equal", the tallest maples must now be cut so as to not oppress the smallest.

And then a sapling sprouts, not taller than the lowest branch of all the others...
