The 13 colonies were not "experiments". They were preexisting local governments that needed to come to agreement on forming a new nation after overthrowing the rule of the British King. The compromises made in the US Constitution were the price for that agreement at the time. The problem is that people in the 21st century still feel bound by an 18th century agreement. I guess the alternative is another civil war, so that might be why the agreement lasts, no matter how shaky and dubious.
