Several years ago, I read an article in
The Atlantic about the risks and vulnerabilities of presidential systems of government that was quite an eye-opener. The author's thesis was that presidential systems are intrinsically unstable forms of government which tend to rapidly devolve into tyrannies.
In support of his thesis, he offered the fact that all but two of the presidential systems the world has seen have done exactly that -- devolved into tyranny -- within roughly twenty years of their founding. Only the United States and (for the most part) Chile had escaped the fate of the overwhelming majority of presidential systems.
Why were presidential systems so fragile? The author advanced the theory that they promote two party politics, which then is extremely susceptible to gridlock whenever the presidency is controlled by one party, while the legislature is controlled by the other. Finally, if the gridlock becomes entrenched such that the government can no longer operate, people start looking for a 'strong man' (as he called it) to take over in order to get things running again. But of course, the strong man is very likely to soon enough becomes a dictator -- a
president for life with unchecked powers.
Again, he was basically describing what has happened to nearly every presidential system the world has ever seen. But please note: We should not confuse a true presidential system with a parliamentary system in which there is a 'president' at the head of government while real power resides in a prime minister.
The author then turned to the question of why the US had survived for over 200 years, while most presidential systems were lucky to stay out of trouble for 20 years. His answer was that the US had (with the exception of the Civil War period) enjoyed over 200 years during which the two parties agreed on the basics and only argued over less than basic things. In other words, the US had been very lucky.
Given the above, it seems to me quite possible that the intrinsic weakness of presidential systems has at last caught up with the US, and that now we are on the brink of going the way of almost all other presidential systems. That's to say, it might not be too long until we, too, devolve into a dictatorship.
