Venezuela has one industry: oil. Oil prices have skyrocketed. ANY Venezuelan government would have a huge GDP increase. Then, of course, Venezuelan production has, reportedly, actually fallen despite much higher prices - because of mismanagenemt and incompetence.
Any numbers coming out of Venezuela right now are, unfortunately, not too reliable. Not because of any malice, actually - mostly because they've rid the bureaucracy of those who could compute them.
Pretty much.
Just taking numbers into account without looking into the economy and its fundamentals, and without looking at other things over which the government can actually make a difference (like criminality rates) can only lead to a partial analysis.
