It may take a little bit of extrapolation, which some people may have difficulty with, but here's a quick list...
1) U.S. dollar / Federal reserve scam
2) alliance between military industrial complex and US foreign policy in the middle east IE "U.S. empire"
3) Use / uphold / enforce regulation to ensure other modes of transportation (which aren't so dependent on gasoline) remain in place
4) Start wars with anyone trying to get away from the petro dollar
