To turn down the heat, we have to end the era of fossil fuels

Donyou realize that the top 1% is creating around 25% of the pollution with their Jets and yacht etc... and they horde moat of the houses to profit from the fact you need housing. And they create food scarcity to rise the prices etc... so yeah keep thinking you'll become one of them some day. Even if you made 1 million a year you would still need to live a thousand years to make a billion.

Oh right the rich are rich because they convinced us to consume all kinds of needless stuff through constant advertising and marketing. And the manufacturing, warehousing and selling of those products all cost energy we get from fossil fuels is the issues. So silly. Eat me.

way bigger than any stupid obvious fix

Yes, we have a societal shift that's required in order to address this issue. It's going to have to be as massive if not larger in scope than the entire industrial revolution and on a timescale more accelerated than the industrial revolution. I would posit, that the rich have the most incentive to maintain the current societal paradigm and have the most access to institute policy that maintains such. And thus, in general, in order to effect such a social shift that is required to address the issues, the rich must either begin supporting policies that put their vast wealth at risk or that the rich must be eliminated.

The latter of that I would draw a parallel to a blocked river to farm fields. Removing the blockage doesn't instantly irrigate the fields. There's still lots of work to be done once the flow of the river is restored. BUT digging all those irrigation ditches does nothing unless flow is returned to the river. In my parallel, the rich are our blockage to the river and removing them doesn't technically fix everything, but it's a step required in order to get flow back.

Eat the middle class!

Sure, but just because we will stop releasing more CO2 doesn't mean it will go down. It will still be there. Ending fossil fuels is the first, necessary step. But turning the heat down will take a lot more work.
