I think it's because I was able to connect with people so well when I was young that I went down this path.
It was just a game at the end of the day. Make the right moves, win the right prizes. But like any game, you lose the magic after a while. And unlike video games, you can't just step back and take a break from doing it, it's an unavoidable part of being human.
But you're not off-base. At this level you definitely lose touch with everything people find "normal." I've found myself not caring about other people or their problems. Why would I?
Group dynamics are emergent behavior that's coded into our DNA to increase survival, prisoner's dillema style. If someone does nothing for me or adds nothing to my life, why would I give them any of my empathy? Can't they fix their own problems? Do they wish some knight in shining armor would ride in and save them? Do they want a handout? My empathy, for free? How selfish is that.
Every problem has a solution, endless complaining gets one nowhere. When I was broke and homeless, I'd get my own hands dirty. Now that I'm comfortably wealthy, I can throw money at whatever problem pops up.
Whatever problems, emotional, physical, mental, sociological, economical, yada yada yada, that you have are your own responsibility. No one really gives a shit about anyone else; all relationships are transactional, and if you're not offering me gold beads, you're not getting my muskets.
Ranting aside, that's a brief intro to my experience and worldview. If any particular piece resonated with you strongly, please leave a reply. I'm always interested in seeing original ideas, how infrequent it may be.
