Earlier quoted context omitted.
> we do need to start curbing consumption You do that by increasing the cost of consumption. Everyone has, even wealthy people, have a price point beyond which something is too expensive for them.
I agree, and what better way than to impose a tax on consumption after X dollars. Or perhaps even a general luxury tax for goods that aren't absolutely necessary for your welfare. Still better would be to start taxing natural resource usage, or even setting quotas with strict penalties. But it's hard to see politicians going along with it and I don't know if it can be monitored sensibly.
I'd go with taxing fossil fuel extraction. Every barrel of oil, liter of nat gas, or ton of coal is taxed. The revenue from these taxes should go towards either a) carbon capture or b) tax credits for lower-income households or c) UBI. The costs of these taxes will propagate throughout the economy and everyone will adjust their consumption accordingly.
