What happened to gasoline in the mid 1970s?

Really don't know why you had to make this so overtly political. The man is a well known and professonal economist by all accepted standands. You can say you don't agree with positions or conclusions or whatever. Or simply that you view things differently, name a different camp of economists.
What IMO is over the line is saying he's not an expert in his field because he worked for an administration who in your view had failed ecomonic policy.

I'm all for discussing how policy and economics influenced the changes in gasoline. But I don't want to see the thread side tracked or shut down. I know its a fine line, and we all have to walk it. But its not that hard.
It all goes downhill as soon as its turned into an US and THEM. THEM is always the delusional, stupid or ignorant and that pretty much ends any intelligent discussion. :(
