Well based on the way you're saying it derailed. That it lasted for 1000s of years. It seems the point which caused it to fail "recently" was speedier and "masser" forms of transportation.
Boats are what allowed slaves to come over. Now long distance instant communication teamed with other forms of even faster and better and "masser' forms of transportation are allowing highly coordinating, mass, long distance "immigration".
Maybe any country worth moving to will NEVER be able to survive this from here out.
