Ironically, because we are too stupid a species to put willingly pit ourselves through any austerity on a large scale. No one is will accept less than they have it seems, even though the only people who would actually need to downgrade their lives are the ultra wealthy. It doesn't make it any easier though because they hold all the power. And they use their propaganda power to tell us to change our lifestyle choices, while they flaunt their own wealth. They tell us to choose more expensive "eco-friendly" or "ethical" options most of us can't afford, and so are encouraged to feel guilty for failing to buy. And they buy them of course, but then still drive million dollar cars and own multiple multimillion dollar mansions.

We've really got to find a way to stop fucking over ourselves like this. And we've got to do it by somehow getting the richest people and organizations of the world on board. Violent revolution has rarely worked long term, and it's slipping further and further away as security technology gets more powerful. Nevermind drones and the inevitable rise of autonomous weapons systems. The "rabble" will never have access to these ordinances. So we've got to get in their heads. Trick them into doing the right thing enough to see that as the challenge to which their should commit their wealth.
