well, if the South had seceded, we would have a liberal government, healthcare, housing for everyone, equal economic opportunity, no history of lynchings - and thousands of Southerners (like Berigan and Weizen) trying to illegally cross the border under the cover of darkness, in order to partake of our much superior Way of Life in the North and West.
we would, of course, have accepted the large migration of African Americans, which likely, at first, would have caused some tensions, but ultimately things would calm down, and of course that block of voters would likely lead the progressive coalition that would run things in this NEW US of A.
and all those old blues records would still exist, because African American culture would thrive even more prominently in our Brave New World. Even more importantly, in this new society, Jazz Musicians would have a place of honor in every community, and be served by great staffs of tall virgins (so you guys might want to move here ASAP).
and don't worry, Jeff and Jim, should you decide to stay in that Southern Nation (named Thurmondia after the late Senator) we would still export all our wonderful television shows for you guys to watch.
