The collapse in the oil price was very much manufactured, the Saudis saved up a few hundred billion dollars at the high price but then they opened the taps on their oil what costs them like $15-20 a barrel to pump and flooded the world with it in order to put all those folks who pay far more to pump a barrel of oil, putting a lot of their competition out of business. That's what really killed the XL pipeline a few years ago, by the time Obama took credit for stopping it the oil price was so low that it was stupid to pipe Canadian tar sand oil that costs like $60 a barrel to produce to Texas. The Saudis stopped their gambit and the price is back up so now it makes sense.
