We already have "the power." People just don't want to accept the responsibility of their own contribution to the demand of said pipelines.
While big business doesn't want to stop building pipelines, nobody wants to stop buying whatever comes out of them, either. It would be fun to see you try to convince the "working class" of the developing world to stop what they are doing and cease their from-behind pursuit of material wealth. You could try to bribe them but I'm not sure if that is what I would call sustainable.
With "workplace organizing" the benefits are immediate and obvious, and the eventual consequences, negative or otherwise, are not. Kind of thing where a wage increase is obvious, but the eventual outsourcing of your job for cheaper labor, or the eventual bankruptcy of the business when the pensions are due, is not.
We face the opposite problem here, since the effort involved (lifestyle changes) and the negative effects (higher taxes) are immediately obvious, while the benefits are neither immediate nor obvious.
Its more like you are trying to convince people to demand lower wages...
The problem itself (specific to AGW) is not even immediately obvious, apparently you need PhDs from multiple disciplines to understand the problem or you are dismissed with the Courtier's reply, leaving you reliant on an Appeal to Authority. That isn't necessarily wrong, but that is what you are dealing with. Manifesting change then depends on establishing complete faith in that authority or consensus, and, in contrast to a pay raise, the only thing you can utilize as motivation for change is guilt and fear. Then you have to be ensure that bad actors won't try to manipulate that fear via groupthink for less noble purposes... We don't have a great track record for that.
Anyway, I sort of think the seemingly fanatical calls for massive top-down solutions to this problem tends to do more to defeat or demoralize individual or bottom-up efforts, as you might promote, and seems designed to evoke increased permissiveness to those who seek mainly to centralize and expand corporate and government power.
