Yes, this

I hate to post a link to an article unless I have some of my own commentary to add, but this article is more-or-less exactly what I've been saying for years.  Here's a teaser:

Put simply, we've learned a lot since 1787. What was for the Founders a kind of providential revelation—designing, from scratch, a written charter and democratic system at a time when the entire history of life on this planet contained scant examples of either—has been worked into science. More than 700 constitutions have been composed since World War II alone, and other countries have solved the very problems that cripple us today. It seems un-American to look abroad for ways to change our sacred text, but the world's nations copied us, so why not learn from them?
