I used to be a Marxist and now a Calvinist, determinism is just how I roll.
But as for the monarchy/democracy thing, I'm not going to argue with you. The primary advantage of monarchies were not to ensure maximum efficiency through a meritocratic system, they simply offered a more stable form of government, at a time when the central power didn't really have any important roles beyond keeping order in his lands.
Of course, that is no longer a relevant issue nowadays, hence why democracy is better (although a constitutional monarch along with a parliamentary sovereignty does have a few plus points).
