Perhaps people who earn their money in petroleum are different. (Then again, there is Arman Hammer — but he got rich by being a communist.)
I have a relative who is the widow of someone who earned his money in petroleum and she is the most lefty of lefties. Of course, she’s in her 80s, lives in a 2 million dollar apartment, has help, and is well meaning and totally clueless. In other words, a typical lefty.
