Reading this title right off the bat, a democratic form of government is the best choice without a reasonable doubt. Theoretically speaking let’s assume the United States is governed by a monarchy. By assuming this, this means that the Thirteen American Colonies did not declare their independence against British Colonies. Meaning no Revolutionary War.
What does this mean?
This means that the United States of America would not be named the United States of America, ideally it would be called British America. People may argue that just like Canada, Britain would have granted the U.S. it’s independence once they realized Britain could not maintain The Thirteen Colonies because of the geography also including the differences in culture and lifestyle in America. If Britain did not grant Canada some of it’s autonomy that would have meant the Revolutionary War would have costed Britain more money, risking debt, starvation, and the Royals in danger of losing their throne. In fact, if Britain did not grant Canada some of their autonomy North America would just be one enormous Britain territory occupied by American culture. America would also be a Commonwealth country making America one of the superpowers.
Interestingly enough, Britain ended up abolishing slavery in 1776. America ended up abolishing slavery in 1865. If The Revolutionary War never happened then slaves would have been able to obtain their equal rights as humans much sooner.
If there were not American rebels then there would not have been a Battle of Fallujah or a war within the middle east. It appears that there would a greater sense of peace if American rebels would just have accepted to dip their biscuits in hot tea and not dump the tea into the Boston Harbor.
All things considered, if America would have been dominated by a monarchy let’s just say decisions would be made much quicker, justice would take place a lot faster, and the philosophy of the citizens would be conformed to an ideology of liberalism, conservatism, and socialism.
At the end of the day, Britain is no longer a monarchy in which would have made British America a democratic rule, eventually.
