Earth's recent climate spiral.

[Jehanne]

Actually:

1. communism really did inspire a whole lot more people than we are willing to admit, even where communist governments are well known to the people the ideology inspired to have committed unspeakable crimes.     It is the failure of those governments to address issues other than their crimes which ultimately undid communism’s popularity.

2.  The promise of communism was never that world under communism would consume less, but rather the society overall will consume much more but the consumption will be more equitably distributed.    Indeed a notional future of unlimited but equitable material prosperity implicitly based on boundless consumption had always been the bait communist governments dangled before people under their rule to justify why communist governments demanded greater conformity, obedience and sacrifice from people under their rule now than appear to be the case in rival capitalist societies.

I'm no expert. I know that Marx, during his day, advocated an end to child labor and also a national income tax.

In any case, the carbon footprint of the United States versus China is clear, and, so, capitalism, at present at least, is not making it.
