Fixing a national government requires identifying a good model to base your new government on. The American government based its original tripartite constitutional federal republic on ancient Rome. Switzerland, partly based their confederate executive council republic on the American government, with some modifications. Both of these countries are known for being extremely wealthy and prosperous, though this has become less true of America of late.
Identify what type of government your country currently has. The political compass is a powerful tool for doing so, with its four quadrants of left, right, authoritarian, and libertarian. Most governments of today are authoritarian left governments. They believe in enforcing religious toleration and secularism on the national population using deadly force. Their school systems are carefully designed to educate students in socially progressive values.
The major issue with most authoritarian left governments is their large debt, and ongoing political conflicts between the different protected groups. Each one wants a piece of the pie, and the authoritarian left government forcibly makes sure that they all do. The sad truth is that if you try to please everyone, you end up pleasing no one. Most people in authoritarian left governments report frustrations with debt, stress, and conflict with their neighbors. Examples of authoritarian left (some moderate, some extreme) governments include France, China, Norway, Italy, Spain, Greece, and Mexico. All of these countries have mild to large political conflicts, and they have to suppress them using the power of force, as authoritarians.
The high debt and slow growth that characterizes authoritarian left governments sometimes prompts a reactionary force from the right. This recently happened in the United States, where authoritarian right politicians are going to be coming into power during the Presidency of Donald Trump. Examples of other authoritarian right governments today are Russia and Singapore. Authoritarian right governments believe that one set of values should be forcibly pushed onto all members of society. They often have international wars, and high military spending. They sometimes have less debt than their authoritarian left cousins.
Sujit Choudhry is an internationally recognized expert in government and constitutional law. Choudhry likes to help government officials fix their legal systems to make them more effective in maximizing well-being and prosperity for the population.
Sujit Choudhry has seen a tendency for governments to get over confident, and then lose their power to their opponents, rather than learning from them. This creates an ongoing conflict inside the nation that wastes resources and often leads to people dying.
