Even in the US only half the population will fly in any year and you can be sure it’s not the poorer half.

It’s not the rich half using public transport, they are only going to benefit from a transition away from private car ownership.

Yeah, the changes required are systemic and go from the top all the way to the bottom, and the things you mention are part of that process, but pricing people out of everything without offering an off-ramp is sadistic bullshit, and the only reason it's a thing is because rich people and stock prices have more representation in politics than the poor and the environment.
