All human societies are decidedly NOT created equal. Nor are they interchangeable in terms of placement in societies at different points on the evolutionary timeline. In other words, you cannot take a bushman of the Kalahari and stick him in Manhattan and expect him to adjust. It's liberals furiously trying to pound a square peg into a round hole while blaming the rest of us that it won't fit.
The fact that we have developed high-speed mass transit does not negate the immutable laws of nature that could swallow all of human history whole in the blink of an eye and leave no trace except ash. We are specks of dust in a universe of unimaginable enormity.
