Wealth gaps are driven by governments benefitting the wealthiest over everyone else

EXACTLY.

They do this, as they themselves are chasing ratings from international ratings agencies.

And legal (as well as some illegal) bribes for themselves.

Ratings agencies themselves have to change in order to distinguish healthy managed degrowth, from recession

Damn right. The best time for the world’s richest governments to stop chasing infinite growth for the haves achieved partially by enforcing artificial scarcity for the have nots was decades ago, but right now would also be excellent.

The importance of tackling climate change and secure the future by doing less. Or doing the same with better use of resources.

Yep. A combination of drastically reduced consumption by ending planned obsolescence, transitioning away from all uses of fossil fuels, and diverting resources away from the dragon hoards of billionaires and predatory corporations towards renewable energy, poverty alleviation, public education, and worldwide universal healthcare would make almost literally everything exponentially better.

We all need to understand climate change and massive wealth disparity are a national security and existential threat.
