Degrowth will happen whether we want it or not. Because fossil fuels are not unlimited, and we are close to the global production peak. We don't have any technology that can remotely replace fossil fuels, and we don't remotely have the infrastructure anyway (it's not just about cars: everything relies on oil).
There are two ways: chosen degrowth is called "soberty". That's not super sexy, but the alternative (where we don't do it ourselves) is called "poverty".
We need to start changing society to degrowth in a controlled manner, for our own sake.
My latest train of thought is going semi off-grid just in case degrowth hits us too rapidly. Big cities will not be fun.
