I think you are thinking of the greens from more than a decade ago. The Greens haven't stood for that for a long time. They are basically part of labor and push for policies for short term rather than taking consideration of the long term effects or goals.
Here is the Greens policy platform.
Tell us about which parts bother you.
The greens having power would probably do more damage to human decency and DEFINITELY more damage to the environment and the prospects of a sustainable future (if you destroy business you can't head to sustainability, you head towards being a 3rd world country or Greece).
Yes, obviously they'd do far more damage than the "growth at all costs", "destroy the middle classes" pro-oligopoly parties.
