Regarding the "Darth Vader" angle, I think the oil industry (like the media industry) is giving their customers exactly what they want. Even the highest executives of these companies are lily white because their job is to efficiently provide the juice which makes everybody's cars run, and people LOVE their cars. If there is a conspiracy to destroy the earth, it's the conspiracy of people demanding cheap gas, i.e. the very people who are griping about the evil oil industry.
Yeah,  we are all at fault,  I have never told anyone different.  What the drivers can't see is that each gallon they buy makes the whole matter worse.  Many people have fallen pray to the greed of the "WANTS"!

 I want a better house in a nice country setting.

 I want the newest Car, Van, or SUV out there.

 I want my kids to go to better schools out of the inner city.

 I want 2 cars, a big house, and green soft lawns front and back.

 I want more and better than my parents had.

 Now everyone wants the same thing.  Everyone that wants it, is now paying for that greed of yesterday, or yesteryear, or long long ago.

We have to to convince ourselves and others that we are the problem, only then can we change.
