I think you underestimate the power of "not my problem" thinking. I agree future historians will judge our governments and our megacorps, the current keepers of humanity's resources, very harshly. However, many of those at the ships' helms are insulated from their own externalities, the consequences of their decisions. And most of the shares are held by others who are similarly insulated, or abstracted away through 401ks and mutual funds. The core of the problem is that our entire system of resource allocation is based on who can make the most money with them and construct the tallest walls around them, not who uses them to better the most lives. For every million lives destroyed by climate change, there is a million more that doesn't care about anything beyond their family, their friends, and their iPhone. A warming planet will make much of Siberia arable, for example. I think the answer to your questions begins with another question: what would make a CEO not use lobbying to resist taxing externalities of his company? What about a board of directors? A shareholder? An "average voter?" When we can answer those questions, we can begin to make progress.
