I hope that you're not implying there is some simple, easy way to define that 20%.
Because in fact there is not.
Not completely simple. Not all one race. But all male, for sure. Almost all poor and urban, though that is not an entirely firm definition. Something about putting a lot of poor and poorly educated people in a small place and not having strong social institutions. You see all these problems in rural areas, of course, but it is never ever as bad or even close. The murder rate for the worst cities is over 50 per 100,000 per year. For must rural states it's under 4.
And if your uncle had been plumbed different he'd of been your aunt...
Hitler was doomed to failure because the whole premise by which he operated was defective. He preached that the Germans were a superior race. That somehow because they were white nordic peoples they were somehow different than others. The only way he could motivate was by having some straw man he could hold up in front of the people to blame for every perceived problem and to inspire them to hate. He gave nothing to the conquered people to inspire them to see him as anything other than a deluded madman. In every nation he conquered there rose up an underground resistance that used every means in its power to cripple and harrass. If Hitler would of won the hearts and minds of those nations he conquered he would have succeeded, but as is, he antagonized them and they turned against him.
Hilter used fear of, and hatred of specific groups to gain power, but it soon became obvious that anyone could be made into a group that would fit a criteria for the death camps. And his system looked on everyone as being under suspicion. Everyone was looking at everyone else with suspicion. One could not trust their family, their friends or their neighbors. The populace was lost any motivation to to keep the system going, and fear was not enough.
