I know I'm not going to gain any friends making the following comments, but I have to speak my piece. If only to play Devil's Advocate.
Re: the OP.
Not trying to rain on your parade. Your idea has potential. However, think about human nature - during a long-term Crisis, who are most likely to survive? The toughest, the most ruthless, the most intelligent. Saying "crime-free, comfortable and safe communities" is one thing. Implementing it is quite another, given the likely population you will be dealing with. Unless you are willing to go as far as enforcing Peace with the bayonet? That will, in turn, beg the question: How many people will be willing to submit? To trade their freedom for comfort and fleeting "safety"? And there will be peace only so long as people fear Official Blowback more than not...
Re: Our esteemed friend from Germany.
My family is German. My wife born and raised there. Our son, also born there, in Stuttgart. We have deep roots in Germany, and speak/read German around the house.
The refugee problem is a touchy one. I, for one, do not approve of Germany - and greater Europe - admitting so many. If the ultimate goal is allowing them to stay so long as their home of origin is in trouble, with the ultimate goal of going back home, then fine. If the goal is to admit waves of refugees into Europe permanently, then no. I am not without empathy, nor am I without a sense of altruism. But allowing so many into Europe permanently is altruism bordering on suicide. It is, I think, self-defeating. In the effort to stay out of war, the EU is inadvertently setting the stage for a very bloody future war in Europe by admitting millions of 'refugees'...
If Europe has a duty to accept refugees, do not those other nations have a duty to not create them?
I was a soldier. Most of my adult life. I have been to war and studied it. One cannot be in the middle of it and not know it's history. After the Peace of Westphalia, wars were the province of the nation-state, and thus was born 1st Generation warfare. This lasted till the middle of the 19th century, more or less, when 2nd Generation warfare eclipsed it. By the end of 1918, 3rd Generation warfare - also known as "Maneuver Warfare" - had been perfected in theory. By the 1930's, it had been perfected in reality.
All of which brings us to 4th Generation warfare. This is important to us because it represents the nation-state losing their monopoly on declaring and fighting war. Political and religious factions, even individuals, now declare war on their own. Those 'refugees' being admitted to Europe are the seeds of future war being sown, same as the "immigrants" flooding into the US in their millions are the seeds of future war being sown over here. They do not vote for, nor advocate for the systems of government that are found in the West, though they easily could. They don't do it at home. They won't do it here or in Europe. They will only stay "peaceful" so long as they are outnumbered. As their numbers grow, so will the violence escalate.
When I was active duty, I had the chance to review a list. It was a list of literally every country on Earth, the breakdowns of their populations and their current state. A friend of mine says the list was produced by US intelligence, and even though I have no reason to doubt him, I cannot remember myself. It was almost 20 years ago, after all.
The more homogenous a nation was, the more at peace they were. Those near the top of the list - Iceland, Finland, etc, were almost 100% homogenous and were at peace. The greater a percentage of "other" in their population, the less 'at peace' they were. As the percentage of 'other' increased, so did the violence - crimes against people, robberies, etc. Then came riots, demonstrations and street fights. Then came terrorist bombings and covert war. Then open civil war.
The magic number seemed to be 40% "other" in a population. Any nation on Earth that had a population of 40% "other" or greater in its native population was either a totalitarian state ruled by a dictator or tyrant, or was a complete repressive police state, or was engaged in Civil War. There were no exceptions.
The 'refugees' who flood Europe - and the West in general - have no interest in assimilating. Applying our cultural values to those who do not share them will always result in failure. And that failure will result in humanities default setting - war.
