There would be one country with mercury in the water, polluted air, the science contained in the bible, ubiquitous guns, no roads, trains, air traffic control and other socialist networks, no government-backed fiat money, no non-biblical choices, lots of dead folks who had no health care, and so on.
And then there would be two civilised, coastal countries with mixed economies in the northeast and west.
Seeing the dreadful life they have created for themselves, perhaps the folks in the middle would wake up. But would the folks on the edge want them back?
