I am not advocating going back to a monarchy.
But, in the past, you could run into situations where a monarch or the relative of a monarch was afforded the opportunity to be an extremely devout Catholic, such as St Louis of France or St Elizabeth of Hungary. They were rare but they existed. They didn’t have to rely on popular opinion because they were royals and that was that.
In a democracy, politicians are forced to appeal to the lowest common denominator or at least a wide enough base to be elected. How does a person with unpopular ethics make it to the top in that kind of system? Doesn’t democracy encourage moral mediocrity? This is one of the big reasons that Socrates was critical of democracy and I can see his point. I don’t see a good refutation to this problem other than just accepting that the negatives of a monarchy are even worse than the negatives of a democracy.
