If folks refuse, so be it, I did my ethical duty in making sure they were well informed.
Worked in OT a long time, an old saying is that you either schedule downtime to perform maintenance or the hardware will gladly do that for you.
It's the same with climate, we either suck the cost of rearranging how we live now or we are going to hit a wall with the foot still down on the gas, expecting constant growth.
I'm not saying degrowthers have all the answers, but any critique should be weighed even-handedly against a realistic view of the shortcomings of what we have now and where it's taking us.
1. How does the OCP “stop” colonialism?
2. If what you mean by “changing the perspective on good and desirable” is restricting who can have children and who can’t, then obviously people are going to be upset with you?
"Optimise" is never a neutral verb, we always optimise /for/.
Growth-above-all capitalists observe, correctly, the correlation between economic output and human wellbeing, and assume, incorrectly, a relationship that is both purely and directly causal and straight-up linear.
What if we optimise for human wellbeing and build a society that works less like a Prescott Pentium 4 and more like an iPhone? Figure out what really matters and then set about doing more with less.
(Answers that will be uncomfortably socialist for some - public-ish goods being more efficient in many cases than private everything, and uncomfortably technocratic for others, but tough...)
Because doing more with more is running out of runway. And in this game, you can't just declare bankruptcy and start again. There's no second chances here.
