When Chavez was the president of Venezuela, they were actually doing quite well. Medicare was free and gasoline was available at $0.1 per gallon. But Maduro proved to be really incompetent. He should just step down and take a flight to Cuba.
Maduro can go away and nothing will be fixed.
Without an increase in oil prices, Venezuela is the same as sub-saharian Africa.
There is no magic cure other than oil, the others are painful and will require years after years of reconstruction.
The oil prices have already recovered and surprisingly it is having no positive impact on the Venezuelan economy. If I am not wrong, Venezuela earns around $140 million every day from the exports of crude (at this price).
