I think that there were several failures here.
The oil is in the ground for a reason.
We will not be around for oil to be renewed.
The refinery is too far away
Rail cars aren't used enough. We've need more railways since so many were pulled up long ago.
The market is fixed against the consumer.
Fracking has problems.
Waste water was not disposed of properly.
Natural gas burn off to fix the price in the natural gas market.
Locally, there isn't (any?) enough pipeline inspectors in the state.
Cities and the State didn't tax enough.
Cities and towns were not prepared for the increase in workers. Public infrastructure such as garbage and waste couldn't keep up. Housing rates were obscene.
Media trumped it up as salvation for people that couldn't find work.
Finally, history will reveal the worst infraction; that the oil boom was ever a cohesive series of events.
It can be highlighted by the lack of controlling the message in regards to employment. That endless jobs & housing were available. Now, when people do leave, what will things look like?
I'd like to see the leasing agreements to know to what degree will they have accessed the oil? Do they need to drill endlessly? Not likely. How many sites are still producing? How many were capped?
Unless citizens recognize their stake in regards to oil extraction, they will just be bystanders. Left with a mess to clean up. No one to turn to.
Look at New Jersey. 39.5 cents on the dollar.
