I agree with the way you portray what has happened in the last few decades but I think it was easily predictable—and in some cases part of the master plan. The environmental movement comes to mind. I also remember back in the early 1980s a relatively unknown Rep. Boxer launching an assault on defense contractors through changes to arcane laws and regulations leading to their decisions to also flee the state. While federal laws, there were related reasons that made it advantageous to get the heck out. There are too many examples of other laws to mention but the consequences should have been obvious to those who look further than the next election, IMO.
I disagree. Utopians are not suicidal.
Few, if any, knew or predicted that more than 10% of a nation would voluntarily emigrate within two generations and even fewer would have predicted the organized capitulation of sovereignty to achieve political gain.
"We had to destroy the village nation to save it" rings in my ears.
