Leveling had it first big moment in 1647 in the agitation for the abolishment of property and privilege by Cromwell’s Roundhead army. Many of today’s liberals and conservatives would be shocked to learn that the Western world’s first socialists were a body of Christian “religious fanatics”.
That is, they were good Republicans.
You do realize that the United States Constitution not only abolishes the class system, it prohibits its officers from even accepting the trapings associated with the ones that do exist outside this country. The Second Amendment contains in it the very language necessary to ENOBLE everyone ~ the right to keep and bear arms ~ the hallmark of the highest class in ancient times!
BTW, the use of the term 'property' in the lead-in piece differs from the more normal American usage at the time which was that 'property' were slaves!
