I believe that the final version of the US Constitution created a balanced political system. Unlike many others at the time, the Constitution created a way that each branch could control and avoid that any other power had too much power.
The American Federation is a good way to balance power because it gives just enough each government needs. The Federal government, at the time of the final version of the Constitution, did not have as much power as it has now. But still is a balanced government system.
The Great Compromise created a functional representation system, with two houses the states and the population are able to be represented and have their interests defended. It is not fair that major states have a bigger representation than smaller states and also it is not fair for bigger states have the exact same representation, this way the Senate and the House of Representatives are a good balance.
