Time is running out before Venezuela becomes a failed state. It is true that a failed/war-destroyed state can be rebuilt, but it takes a long time, it takes a powerful political center, it takes outside help, or at the very least no more meddling. Before writing about any possible political solution we need to discuss the distressed economy and how difficult it would be to restart it.
When Maduro was elected in 2013 he could have taken a few token measures that would have avoided the extent of the crisis today. He did not, and took even additional wrong steps. Then this mismanagement was magnified through a nasty political crisis and recently US sanctions.
The root of the economical crisis comes way back. Even before Chavez. In a way we could say that Chavez invented no new deleterious practice: he just magnified them to unsuspected levels. It is too long to review that descent into economical hell, books have already been written about it. Let's just look at today's situation.
