> But here's the thing: the reality of current power in western countries is that it has been completely captured by large corporations and capital.
The economies in non-western countries aren't any different, often just less perfect versions of western market economies. (And sometimes, like with Taiwan or Singapore, more perfect versions.) The important point there, though, is that even imperfect market economies have led to enormous increases in prosperity for non-western countries. Market reforms in countries like India meant that GDP per capita more than quadrupled from 1999-2019, while it less than doubled from 1979-1999.
The climate justice folks, by contrast, want people from the developing world to rely on "endogenous and indigenous technologies and innovations in addressing climate change" so they can "develop, access, and transfer environmentally sound, socially acceptable, gender responsive and equitable climate technologies." https://www.peoplesdemands.org. (Luckily, countries like India are going with Thorium reactors instead: http://large.stanford.edu/courses/2018/ph241/wolak1. And that will be the ironic outcome of climate justice efforts. It will be essential to get India and China on board to address climate change, but those countries are too smart to jump on that bandwagon.)
Ironically, it is precisely the dichotomy you mention that justifies the hard-line opposition of the right-wingers. If tweaking market economies is not the solution, and the alternative to the status quo is "revolution," then it is utterly rational to seek to protect the status quo.
