> Give the lower economic classes a larger voice in government and I think you'd be surprised how many would vote for things like investment in clean energy.
What are you basing your belief on? Are you saying that people who have never had the time or means to get any sort of education or ponder over such subjects will still understand why society should care about the environment (and many other things, like technology advancement, health, research, military etc)?
I don't believe that's the case and I just can't see how you might have arrived at such conclusion (which to me amounts to: you don't need any sort of education to arrive at these conclusions).
In practice, I see a lot of people in developing countries who live in a democracy and hence, already have a voice just by being able to vote, tend to vote for candidates who have populist agendas which almost never include green energy (when that will cost the population) and forrest preservation (instead of jobs and more agricultural/logging output) or anything not directly related to their immediate wellbeing (sometimes, against even that).
