selfishness, laziness, lack of self-awareness, lack of shame, etc are obviously universal traits. But cultures absolutely reinforce them to different degrees. Many cultures around the world are built around the sorts of behaviors we both described.

Whereas other cultures have at least some (if not a lot of) resistance to it - eg publicly ridiculing when people step flagrantly out of line. This is good. My impression is that British culture is like this - "taking the piss", or worse, out of people whose egos start to get too large

Edit: what about this comment could possibly be worth a downvote...? Not that I care about points, but it just seems to be an objective assessment of human nature and cultures, without even singling out any cultures that need improvement.
