Difference is, you don't need to build a gulch, to opt out of Venezuela's economic system. You just need to leave the country. Over 2.1 million people left already.
And, unlike with Mexico and some Central and South American countries (where it's the poor emigrating to the US, seeking menial jobs), this is the upper and middle class, leaving and settling in pretty much every country in the world, outside maybe Africa and some of the bad parts of Asia.
That's actually one of the reasons why the crash is happening so quickly, compared to other communist states. These idiots forgot to build a giant wall, guarded by men with guns and attack dogs. So all the productive people just packed their bags and took a plane out of there.
P.S. the third stage of the migration is actually whoever is left...lower middle class and the poor, crossing the border into Colombia (some staying, some making their way to the US through smuggling routes).
