@blatham,
Well, we all have an understandable human tendency to cling to our achievements, whatever they may be, and whatever the merely good fortune that may have attended getting them. I've found that it isn't very hard to find people who are smarter, better off, and better at the things I treasure in myself, than am I. The really strongest people I have met or gotten to know tended to be very aware of that, and aware of their own limitations. Humility is indeed strength, and the self-promoters of this world often don't have it.
I agree with you about the careless use of language and have been guilty of that myself.
I finished four years of grad school with a dim view of many academics, and that was in the relatively prosaic areas of Mathematics and Engineering. I have since learned that the best of them are usually the least inclined to self-promotion, pretense and vain posturing. My (superficial) impressions of Scalia marked him as one of the very best.
In general I believe these character traits dominate the worth of people in all the walks of live I have encountered. The potential for the exercise of power or influence can, of course, magnify the good or harm that can result.
While people do indeed tend to congregate in hierarchies, as you suggest, these hierarchies come in diverse forms involving many things beyond just raw power or wealth. Moreover, I strongly believe that individual traits and behaviors generally count for far more than the facts and mere perceptions of the group, values, behaviors and identities that are so fashionable today, including the presumed class values that so pervade modern political discourse.
While wealthy and powerful people can indeed exert influence on government policy and action, it is easy to see that they are distributed fairly widely across the divides of most current political issues (Koch bros. vs Soros, etc.). The same goes for non governmental institutions, including corporations, labor Unions and foundations of various types with respect to political contributions. I believe the most prominent exception to this is with contemporary academic institutions (particularly those in the so-called political and social "sciences", and a large fraction of the various media institutions. These appear to be decidedly biased towards materialism and increased government managed control of individual behavior.
