Hey there!
Monarchy is the best form of government. One reason is that it unites the people. Giving people a figurehead to represent all of the people, not just a political party, can really help steer people during hard times. Another reason is that it is cheaper to have a monarchy than a republic. If you compare the costs of European monarchies to the cost of American and French leaders, there is a very high difference. A third reason is that countries that have monarchies are less corrupt. Politicians are seen as untrustworthy, especially when they make promises before an election and never follow through.
Hope this helps!
