This is just not true, unless you're counting manufacturing as part of the pollution from the billionaires. We consume the products produced in those factories, so we're not free from that blame.

Take a look at the Cargill family, 14 billionaires. From the wiki about the current CEO:

In 2019, former U.S. Congressman Henry A. Waxman, in a report by Mighty Earth, called Cargill "the worst company in the world" and noted that it drives "the most important problems facing our world" (deforestation, pollution, climate change, exploitation) "at a scale that dwarfs their closest competitors."

Do you think that is because they use every cent to burn coal and oil in their backyard, or

do you think it is because they produce and sell products to consumers which can not be produced without harm to the environment?

99% of the planet could produce zero pollution for the rest of our lives and it wouldn’t even make a dent in the amount of pollution created by the billionaire class.

How do you think they would create that damage to the environment if nobody would buy their products?

I'd be very interested in the source for this...

America’s richest 10% are responsible for 40% of its planet-heating pollution

The emissions of the middle class are also a huge problem and will have to drop to 0 as well.

The general public has sadly been guilted into the idea that dealing with the vast majority of pollution is their problem. Don't get me wrong, there is some personal responsibility, but much of it is out of our hands.
