I've always liked that speech since I read it. This passage is very poignant. It works in reverse as well, both lead to a downwards spiral.

"Looking back over the past years of Germany’s decline, we come to the frightening, nearly terrifying, conclusion that the less German men were willing to act as men in public life, the more women succumbed to the temptation to fill the role of the man. The feminization of men always leads to the masculinization of women. An age in which all great idea of virtue, of steadfastness, of hardness, and determination have been forgotten should not be surprised that the man gradually loses his leading role in life and politics and government to the woman."
