We need a glut of cheap liquid fuels. We should either "trade" our "expensive light crude" directly for gasoline and diesel; or ban the export of finished product.
Believing the demand curve of economics will rule while pretending the supply curve doesn’t exist only works in fantasy land.
Shutting down our refineries that currently produce a surplus of products while we import more crude oil than we need isn’t going to help us either. It helps the trade balance, keeps a surplus of refinery capacity in the US, keeps more jobs in the US. Why do you want to send that work to other countries?
Do you believe plastics, food, cars or anything else would become cheaper if we banned their export? Or would we simply stop producing as much because people don’t invest their money with the plan of losing money?
