Mexico and Brazil aren't that much far behind Venezuela, and might well be in a similar place to them if the regional hegemon had interfered in their internal affairs to the same extent.
Mexico and Brazil can at least still afford to print money, it seems. That simple action is beyond the ability of the Venezuelan government at present, as their inability to pay suppliers for the previously issued notes makes it impossible to get any more printed. That's what happens when the gold reserves start to run out. How did Chavez's daughter get so rich, anyway?
The diminished flow of Mexican refugees to el Norte indicates that things are very much better economically despite the high crime rate.
(btw, Spurs are just putting on a show here this morning. lovely stuff.)
Constantinople fell because the Byzantines spent nearly a millennium taking power and wealth off the poor and spending it on the rich, so that when the crises hit they were progressively less able to deal with them. This followed the Romans destroying themselves from doing the same thing, and was followed by the Ottomans doing it as well. The same phenomenon is seen in historical Muslim regimes so often that it is almost a cliche, and led to the one conflict honoured with the title of Civil War over here.
This appears to me to be entirely consistent with the point of the essay that was so bollocks a brief time ago.
Others may differ, but that's what I see.
