Ok, afaik we're evolved to be programmed by culture -- we're more optimized to get respect from others than to earn money.

But... I wonder how much of this is an effect of an inability to see some things about other cultures, because of political correctness?

Some differences are just shocking to modern westerners.

If you have read a bit of mideaval history, you realize there are some similarity between traditional clan cultures and modern organized crime families; e.g. the lack of humanity assigned to outsiders. This is not possible to discuss, since some places on the planet still have similar societies.

Another example is that tolerated pederasm (greek/roman style) is not gone from the planet. It is hard to know, since it isn't really discussed even by e.g. NY Times.

(All these are obvious examples from my own media, yours might be different.)
