This whole "return to the bilssful days of yore" mentality is a bit ridiculous. It's a sociological version of the "grass is greener" syndrome. Societies and the governments they create evolve over time. It would be no less practical (or desirable) for us to devolve back to our hunter-gatherer days.
This is a great book that helps dispel some of the nostalgia for "the good old days." Read it and you quickly realize that things Way Back When just plain sucked....
