Fair enough - you’re not completely wrong, looking at it from a wider perspective.

I can’t see that ever happening however - the majority of relatively wealthy people are unlikely to ever accept a reduction in their wealth even if it solves climate change, world hunger, whatever.
People want to see an easy solution that doesn’t affect them directly. Much more likely is the rise of the far right, riots, etc.

Fixing this problem requires more redistribution of wealth than degrowth. Workers should be paid appropriately for their work, and those at the top should get a smaller slice of the pie.

Capitalism which means that business owners are free to make billions yet those who produce the goods go hungry, is utterly intolerable.
