There are a lot of folks who can't understand how we came to have an oil shortage here in the USA. Well, there's a very simple answer.
Nobody bothered to check the oil.
We just didn't know we were getting low.
The reason for this is purely geographical.
All the oil is in Oklahoma, Texas, Louisiana, Wyoming, etc.
All the dipsticks are in Washington, D.C.
