I have a theory that ultimately people are more or less the same. What motivates them is what they believe to be is best for their own self interest. However their theory as to what may be best for them can be vastly different. With that said liberals, conservatives, libetarians, neo-conservatives.....they all aspire for the same goal....to look after their own self interest. A government can actually get away with quite a bit when it comes to trampling on individual rights so long as they can deliver prosperity. As much as I value freedom of speach, press, due process, and the pursuit of happiness I value 3 meals per day and enough gas to keep my car rolling even more so.
Take for example Irak. I bet those "Sodom Insane" days with those United Nations food rations and enough electricity to keep the lights on look pretty damn good right now.
Once PO hits the first nations to feel the pain will be the third world since they pay more for oil relative to their income. How will these governments control their restless populations? History has shown that no government, no matter how brutal and authoritive, can control the masses when it hits the "breaking point". I think OPEC will be an "interesting" place once even their oil runs out. Most of those governments are despotic regimes who stay in power buy bribing the masses with a welfare check paid by oil revenues.
There's a popular belief that dictatorships do not have to worry about public opinion. Nothing can be further then the truth. If that were the case then why do dictatorships invest so much in propaganda? All governments stay in power by convincing their populace that it is in their vested interest to keep the current system rather then overthrow it. Once PO hits it's going to be difficult for some governments to continue doind this.
