My point of view is that "we have to curb emissions now before consequences grow too dire" is not a "luxury belief": the actual luxury is/was consuming fuel and fossil products without ever paying for the externalities. It was a luxury we could not actually afford at any point, basically just got it on credit in the past, and all that credit is coming due within the century.
> Why haven't shareholders of energy companies also made sacrifices to save the environment? How come only the consumers have to?
Because overall most of the benefit did go to consumers. People basically got a gallon of gas for 30 cents in 1960 when it probably needed to be a dollar or more, but companies like Shell only ever saw a small fraction of that retail price, and there is absolutely no way you could claw back that difference (or anything close, really) from them.
> Do you understand why people are pissed off with the switch?
I do understand the feeling of getting things denied that you took for granted, but I have little sympathy for selfishness.
