This happened in class the other day. There was a discussion of the anti-growth position taken by some environmentalists. The assigned reading said that, broadly speaking, there are two theoretical options, to either resist economic growth in the interest of sustainability or prioritize growth but adopt various regulatory and technological palliatives to try to avoid ecological harm. The authors clearly favored option #1. The claim was made that, despite its virtues, this option was uniformly rejected by those in power, whose ideological blinders wedded them to never-ending growth.
I raised my hand. When called on, I pointed out that, while not explicitly motivated by an anti-growth philosophy, those in power have repeatedly adopted policies whose effect is to render growth unlikely or impossible, especially in Europe but to some extent also in the US and elsewhere. De-growthers stumble when asked what measures to take, but the most powerful instrument is right there in front of them: austerity.
