We've made crappy amendments to the Constitution before (Prohibition era, anyone?), and it's definitely experimental in nature. Our founding fathers had no idea what to do when the Articles of Confederations bombed, and this was the best they could do. But stuff has evolved since then, and the Constitution has evolved with it - but not always in the best way. We're still clinging to some outdated stuff that we shouldn't be clinging to and letting go of some things that we should hold onto. Finding that balance is hard, especially when you can't just say "Let's write another one and try to do better" because when we wrote the first one - we were all kind of in agreement - but the US isn't in general agreement anymore. Every state, every city, every district, every county, every politician, every individual ever wants something different. The fact we've tried so hard to adhere to this thing for as long as we have though is still kind of admirable, but I wholly expect a revolution of some kind to happen several years down the line. Maybe not in my lifetime, but maybe my children's.
