Why is a a green collar job is not just a retooled blue collar job?
The old Division of Labor ignores the intricate web of life, and is what got us into our current environmental mess in the first place. The Green Collar Movement can't afford to perpetuate the destructive old division of thinking that is integral to the division of labor concept.
I have plenty more to say about this, which I'll add when I get a chance.
