I used to think this was more like a conspiracy. It's very far from it, though. Years ago, even one of the most powerful US Government officials, who used to be labelled the most powerful man in the world, and the US's highest ranking technocrat, Alan Greenspan, wrote that the Iraq War was largely about oil.
Greenspan was an economist, and economists sometime us an analogy of looking at macro topics through the framework of a household, i.e. a national budget vs a household budget. Using that same framework, if one neighbor went to war with another over natural resources on their block and declared "he had a gun, a very big gun," as the reason -- and conveniently after the house was broken into but with nothing connecting the perpetrators to the victim, that would be clearly illegal, and probably viewed as insane.
I think those of us from America are very lucky to live in a country that places high relative value (though far from perfect history) on human rights and civil liberties, and it's likely a large reason we are so successful. I want us to keep improving on it instead of devolving into something less.
