True enough. But citizens of the US should take note as well. We are not immune from the problems of Venezuela and other fledgling 'democracies'.
The US has been trending away from representative government for some time now, the buffer between the desires of factions and the power to enact those desires is eroding. It started with the war between the states and the consolidation of federal control. It continued when Senators became elected by popular vote. The individual states are largely irrelevant in our federalized system. The 2000 election left many calling for 'popular elections' and doing away with the electoral college. I'm sure there are countless smaller such events that I have overlooked but each is a step away from the republic we started with and toward the chaos we see in so-called democratic countries.
The author of the original piece asks "Has Democracy Failed?". Of course it has. And it should come as no surprise. I humbly suggest the author reads at very least the Federalist Papers, particularly #10.
