It is very strange idea to equate life experiences gained before 18 of people born in 21st century in 18th century.
Also, as outsider, I would never understand US fascination with "Founding Fathers". Some folks born about 300 years ago and somehow having answers to all the questions for all the times. Back than this country was a backwater colony which barely started industrialization. Overwhelming majority of population lived out of sustenance farming and majority of trade goods were products of slave labour.
I mean, it is what it is, but where this yearning for glorious past which never existed comes from? Like, life in USA became more or less good only several generations ago, after the country became giant economical winner of WW2. And it did it by investing heavily into helping allies, not building isolationist policies.
