Considering that the oil companies bought up the trolley companies, and shut them down, I would argue that without those particular billionaires, we would still be building walkable cities the way we did for centuries, until they decided that cars should be essential, but a luxury at the same time.
Edit: this is specifically applicable to the US
Sure - blame Rockefeller, Henry Ford, etc. for that. Also e.g. Robert Moses, not that he was a billionaire. But they’re all dead. They’ve been dead.
Is America’s suburban sprawl the fault of Bill Gates in particular? Or Bezos, Musk, or Dell?
