Degrowth

There are absolutly policies, which are in effect enabling degrowth. For one things like a well run cap and trade system(no offsets) for emissions, working hour limits and other worker protections, public health care to take out risks of working less, earlier retirment for workers, enabling sharing of resources with liberaries, public transport and so forth, and quite a few more. Sitting back and relaxing is certainly a viable path, but it is not like politics can not pay its part.

Also for the last point, the key metric is per capita income. An Indian billionaire is just way worse for the climate then an English bus driver. The narrative should be from rich to poor no matter what and the middle just transitions to green energy. You get a lot of problems, when using the West vs rest of the world. For example China and the EU have pretty similar per capita emissions today.
