Wow, Larry, thats a great article. Great specifics which were carefully avoided by the standards.Just as an overview argument, American Exceptionalism is, IMHO, merely the fact that the American Great Experiment was - an experiment. It had to deliver the blessings of liberty or be a failure. To say that America is not exceptional is to say that it is a failure.
But to say that America is a failure flies in the face of the historic American Immigration phenomenon. People do leave America - but people want to come. Yes, land ownership is more available here - in places. But even that is an artifact of the domestic tranquility established here. And yet we see anti conservative activism subverting tranquility, a government working against its own authority.
On land ownership WITH WRITTEN TITLES AND DEEDS we were not alone (most of Europe had this) but unlike all others we had available land. Every new restriction Zero places on the country is designed to reduce land and home ownership.
