Then blame the Ford executives which keep manufacturing and marketing these cars, not the drivers.

So only executives and rich people should be held accountable? Exactly how rich must one be?

I’m basically just shifting the responsibility from the consumer to the people with the power to influence said consumption. This is basically just extending the logic of “If everyone is making the same mistake, blaming every individual is futile. Perhaps the system should be altered in such a way which makes it harder for people to make this mistake in the first place”.

So to answer your question: “How rich”: Rich enough to own significant stock in polluting corporations.
