There's nothing surprising about it. There is at least one recent, well documented case of mass emigration due to the economic collapse of an authoritarian regime.

Seems like now could be a smart time to get back to Venezuela. Where are these 10M barrels going to come from for the west? And now you have Saudis not entirely taking USA's side in this conflict.
