Your framing, that no collective action can ever include reduction or sacrifice, implies this is an inevitable and fatal path we cannot come back from.

I hope you are wrong that nothing requiring sacrifice can ever be accomplished.

The only time I can think of that democratic populations have made large and sweeping sacrifices have been when they’re actively engaged in total war. And even then, it usually has to be mandated and enforced pretty ruthlessly by the government.

We simply did not evolve as a species to make large personal individual sacrifices today in order to benefit billions of strangers decades in the future. Never going to happen.

The options here are technology saving us, or eco-totalitarian governments controlling a huge portion of the world’s population. Nothing else will work.

This sacrifice involves putting millions back in poverty. I don't think you understand what I'm saying.
