Definitely the 20th century will be known as the Little Dark Age. I think this is exemplified not just in politics, but also in fashion and dance/music. The clip below shows a man and woman being dressed in clothes of every sub-period from early 20th century to our times and doing the popular dance moves of the time.
I can’t really comment about the clothes (although to me, they eventually start looking not just more casual, but also more random and less thought-out), but after a certain point (after the War... or, should I say, after the reign of FDR), the music becomes more like sounds of a grandfather clock falling down the stairs, while the dancing looks increasingly more like epilepsy.
(This video obviously shows a man and a woman dancing. In the later parts of the video, the dancing is somewhat suggestive, but not pornographic. One could argue that since one is watching this video for illustrative/educational purposes, it's not, strictly speaking, ossur, but those who are makpid about such things, beware.)
Don’t get me wrong. Nobody who has seen me dress could ever accuse me of being fashion-conscious. My idea of a comfortable clothing is jeans with a striped short-sleeved collared shirt (and your regular penguin look for Shabbos with the simplest shirt and shoes possible). And my idea of dancing is a bunch of men in a circle with hands on each other’s shoulders.
Western culture is not my culture. And a spider’s web is not my idea of a house. But I can objectively observe that a spider’s web is becoming more intricate and laid with meaning or purpose as the time passes... or less so.
