Why does the American form of government work?

Federalist Papers No. 10:


"No man is allowed to be a judge in his own cause, because his interest would certainly bias his judgment, and, not improbably, corrupt his integrity. With equal, nay with greater reason, a body of men are unfit to be both judges and parties at the same time; yet what are many of the most important acts of legislation, but so many judicial determinations, not indeed concerning the rights of single persons, but concerning the rights of large bodies of citizens? "


"In the extent and proper structure of the Union, therefore, we behold a republican remedy for the diseases most incident to republican government. And according to the degree of pleasure and pride we feel in being republicans, ought to be our zeal in cherishing the spirit and supporting the character of Federalists."

Federalist Paper No. 51: 


"In order to lay a due foundation for that separate and distinct exercise of the different powers of government, which to a certain extent is admitted on all hands to be essential to the preservation of liberty, it is evident that each department should have a will of its own; and consequently should be so constituted that the members of each should have as little agency as possible in the appointment of the members of the others."


"A dependence on the people is, no doubt, the primary control on the government; but experience has taught mankind the necessity of auxiliary precautions. This policy of supplying, by opposite and rival interests, the defect of better motives, might be traced through the whole system of human affairs, private as well as public. "

RESPONSE: Why does the American form of government work?

Based on the passages above, I would say that the American form of government works essentially because of the division of many separate branches concerning all forms of government that work with separate factions of commerce, etc. But the reason that this particularly WORKS, as shown in Federalist Paper 51, is that the members of their respective branches are able to be dependent on each other, but not TOO dependent, so that there's a balance of power between them. This balance of power is constantly "checked", and it is because of this that liberty is preserved, and the government works.
