I predict as we move along the course of time that more and more of these type situations will arrive here in the United States where people will try to escape the "Detroits" across the country. And as society and civil order continues to decline the solutions will only grow in number and with unique ingenuity.
Actually it is nothing new, except it continues to evolve. It used to be "White Flight", now it has more to do instead of getting away from color, and more to do with getting away from people that "dont really give a damn", "people that dont really work", "people that are in the US only for a paycheck and could give a rats ass about being American". I spend many weekends now out in rural America and it is amazingly refreshing to not see spanish graffiti everywhere, not really be concerned walking on a downtown street at night of being mugged or approached by whacked out druggie homeless bums....and sure there are meth labs and some crime in the country......but nothing like where "the problem" is. More and more people will want to escape "the problem"....and they will find a way. Especially as we move into the new era of more and more people being able to work from home. This will allow people much more freedom on where they can live and not be concerned with living in locales because of rush hour drive time.
None of "escape the non-sense" solutions will be exactly alike, but the movement will continue as people try to escape the "new values", the new inhabitants of large metroplotian cities that they have very little in common with including language, history, and taking pride in the American culture. My niece and her husband recently picked up and moved her family to the Ave Maria, Florida community. And sure Ave Maria will not be perfect (where is?), but for them it is proving to be a great fit for raising their young children in a better environment than Los Angeles.
