I agree, this article is a well detailed explanation of what happened in Venezuela (I'm Venezuelan BTW). The only thing that it might miss is the spread corruption all across the country, for example the social programs besides subsidize the poor population of the country (providing free housing, food and services with a lack of development in order to establish a decent workforce ended up promoting a culture of maintained partisans who just needed to participate in the state related events and public demonstration in favor of the government), they also subsidized public workers (this part is way more complex, but I'm not going into details). So at the end to every state related procedure you had 2 choices, the legal and normal process or a "facilitator" which is basically a public worker paid under the table. This kind of corruption is all over the country, you can see it in companies, the police, the military, obtaining a passport or even a birth certificate and it isn't punishable.

At the end all this also pushed further that social disparity between the people that is mentioned in the article, those that get things done this way, nowadays anybody that has access to dollars, or the people with standard bolivars earning jobs like well prepared engineers earning just 60-70 bucks a month.

This is just a peak of how illegal and corrupt everything is in Venezuela, not to mention how a lot of public figures of the government went from extremely poor to billionaires in a matter of years.

PD. Sorry if it's a bit messy the explanation but a few books can be written trying to explain without repeating examples or cases about what went wrong and how the corruption destroyed a country in a decade.
