For sure, I think the patriot act was a turning point in trust of government in the US. It filtered though to our government in Australia during the Howard years. Similar to the US, around the GFC we had a hopeful change of government, but that hope for progressive values (Obama for you guys, Rudd for us) turned out to be misguided. I tend to think of those “centre left” governments as representing managed societal decline as opposed to the accelerated decline of the right wing parties.
Your point about the ozone layer response is very relevant to our expectations of solving climate change. I think replacing CFCs was just low hanging fruit, which I didn’t understand as a kid. I just assumed if we kept recycling and not consuming so much it would put us on track. So naive.
