I just started reading 'Mein Kampf' again and there are of course some brilliant quotes in there. But upon my reading I saw something that paralleled our modern society. While that happens a lot in the book, this one stood out, because it seems so relevant right now:
All really significant symptoms of decay of the pre-War period can in the last analysis be reduced to racial causes. Whether we consider questions of general justice or cankers of economic life, symptoms of cultural decline or processes of political degeneration, questions of faulty schooling or the bad influence exerted on grown-ups by the press, etc., everywhere and always it is fundamentally the disregard of the racial needs of our own people or failure to see a foreign racial menace. And that is why all attempts at reform, all works for social relief and political exertions, all economic expansion and every apparent increase of intellectual knowledge were futile as far as their results were concerned.
The nation, and the organism which enables l and preserves its life on this earth, the state, did not grow inwardly healthier, but obviously languished more and more. All the illusory prosperity of the old Reich could not hide its inner weakness, and every attempt really to strengthen the Reich failed again and again, due to disregarding the most important question.
People back then FAILED to address the problems of multiracial societies and diversity. Pretty much the same thing as we see today.
