I feel like this is an extremely unpopular opinion but I really don't think republicanism was a step forward for humanity.
Monarchy is the most intuitive form of government. People tend to take care of what they own, and politicians have no incentive to leave anything better for the next generation because they really have no stake in their country. Their legacy dies with them.
A monarchy with constitutional (and familial) checks and balances is vastly preferable to a republic where the foreign interests run free and loot the taxpayers. It's pure and much simpler. No Congress, no Supreme Court, no ridiculous sham elections. Everyone knows who's in charge and what the rules are.
Totalitarianism is what happens after you get rid of the monarchy. Russia, Germany, France etc were all way more free under the monarchy than the regimes that replaced it.
The only reason it looks that way is due to the direct Influence WE the Americans had on Europe in WW II....
Had we stayed out of it, Europe would have flourished, the Bolshevik Influence would not have spread its Communist tentacles across Europe and things would be much different....
Had we fought alongside the Germans, the entirety of Europe would have become Republics, in the same manner we had Republics in the Early 1800s, and Communism would have been Crushed in Russia, BEFORE it spread all over the World....
There is little difference between Monarchy and Communism, both become despotic, and Totalitarian, and neither is helpful to the Common Peoples, mainly due to the Oppressive Nature of each....
