This is so stupid it makes me worried for the human race that people actually fall for that. Do people honestly think that the problem of emissions goes away by taking out the people owning the companies producing the emissions? Isn't it extremely obvious that the same companies will produce the same emissions regardless of who owns them as long as the demand for their goods, services and laws governing them stays the same?
I mean sure, lets blame the owner of exxon for the emissions caused by cars and powerplants. I'm sure people will enjoy riding to work on a horse amish style if it means limiting global warming to 2 degrees instead of three, how about you pitch that idea to a large group of people an see how that goes.
You know what would actually help? Electing the right people. Not just caring about this on election day when you have the choice between two shades of shit, get the right people primaried. But you know whats the truth? The truth is that it's not the billionaires fault. The truth is the majority of people don't care about saving the planet, not if it inconviniences them and thats why democracy doesn't nip this in the bud. Because it works. It actually represents the people and their will and the people who care are represented by the guys that loose by 30% in the primaries, as in getting 3% instead of 35%.
You take out the billionaires and the industries will be run by the workers, the state or whatever anarcho socialist conglomerate you can think up, but nothing will change. Because 90% of people are too busy with their own little lives to care about 3 degrees global warming and nothing will change that.
