My academic training has taught me the scientific method: question, the formulation of one or more hypotheses, the verification of this by experimentation and the respective conclusions.
This methodology can be used in many other aspects of life. For example, if you own a business and want to hire a good manager, you make a series of interviews, evaluate the curricula and make the selection. Then you start your trial by placing the chosen candidate running the business. If something goes wrong you restart the process. If everything goes well, you have the confirmation of your hypothesis and while the results confirm your initial expectations, the chosen manager will be in the office.
A country is no more than a large company with very specific characteristics and also needs a good manager (government). When the manager does not generate the expected results, it is possible to replace it with the elections.
So, results of their performance are the key issues to keep them in place.
However, when you think about inspiration (the company’s founder), when you think about the guiding rules of the company or its representation, you never think about someone to be replaced periodically. The company’s founder and their heirs have a mission for life.
Let us return to the country and who should represent it. First the republican model: we formulate a hypothesis (we vote for a candidate), test it and, if it goes badly, we don’t re elect him. So far so good.
But imagine that runs well. The Republic, benevolent, lets elect him again, but then in the name of a supposed turnover and detachment of power, we have to start all over again. It seems to me clearly a bad choice.
However, the monarchies choose someone who knows the country, the people, their culture and social dynamics. The monarchies choose someone who thoroughly understands the teachings of the founder, someone who can truly replace it with stability, competence and without any self-interest.
This model is, beyond doubt, the one that guarantees the right choice for the highest representative of a country.
A queen or a king have a mission and commitment for life!
