I see the Greens much as I see UKIP. Essentially a single issue movement with other bits tacked on.
I think you could just as easily argue that it is the 'mainstream' parties that are fixated on the single issue of economic growth at any cost.
Those of us who never made it into the rentier class know the part that we are to play in this 'economic growth'- either insecure sporadic employment for longer hours and longer years with less pay, a steady diet of humiliation rituals and institutional abuse from the job centre, or vagrancy and destitution. In fact the way things are heading it'll probably be all three at once.. already is for some..
..and the NHS are left to deal with the fallout. Then the drugs companies make huge profits from marketing huge quantities of bogus remedies with weird 'side' effects which get pissed out of patients and end up in the drinking water, so we are all 'on' them even if they were never prescribed for us. Hell- even the 'wild' animals are on them. The oceans are so full of plastic that there are gyres the size of countries that are navigation hazards, and the marine fauna choke themselves. The stomach of an Albatross contains half a dozen 'disposable' lighters.
... I could go on, round in a circle back to where I started. And I could do that by any number of routes of varying length. If all that is a 'single issue' that can be put aside while we concentrate on something more important, like ticking boxes to help decide who gets the gig of ensuring continued profits for the shareholders and stakeholders who would seem to wish to continue this craziness until the planet is once more a barren radio-active rock, then we probably deserve whatever we get.
