Autocratic regimes will bear the brunt of falling oil prices.
Personally, I could care less that our adversaries are on the verge of being bankrupt.
I hope the price of oil drops a lot further.
If your job was selling or building pumps, pipes or any of the other many items or services purchased by the US oil industry, you would probably care a bit more.
I'm not as confident as you are of a positive outcome. In the US, will we be replacing high paying jobs in the energy sector with jobs for people to sell cheap junk from China? What about emerging nations which are building their fledgling economies? Will lower oil prices ruin their economies? Who will buy up the energy related companies when they go bust? Will the US consumer again end up in even deeper debt, buying vehicles and houses they can afford, but only because of lower fuel costs? What happens to the booming economies in oil-producing states? Will destabilized countries cause even more terrorism issues?
This is unchartered territory.
