The prosperity you reference was because there was a strong Union. And you don’t remember any history correctly only as a mint-julip drenched compendium of crap.
See Washington’s Farewell Address for the warnings of our greatest president against the poison of secession. That was what the document was really about.
I might “know the rest” but you apparently do all you can to substitute falsehood at every step of the way.
I think I will let those ignorant comments just stand for all to see.
