After reading through the whole thread I think I get what you're saying.
I agree that "might makes right," but I would also say that, increasingly more these days, "right makes might."
If you're doing something bad, it's going to catch up with you. Either through protests or divorces or revenge of another sort. From what I can tell, being "unethical," is, essentially, taking what isn't yours and being a selfish dick about it (taking life, money, love, property, etc). Though there's generally always unethical things happening, just as often those who are being unethical are getting a comeuppance of some sort. Negative behavior begets negative reactions. Tyrants fall, cheaters get dumped, flakes get fired, and so on.
Yes, those in power can attempt to crush any insurgence, but in the end revolution always occurs. We haven't seen a big, righteous revolution in a while, but they definitely happen, otherwise we'd still be total savages.
You can see there's a larger shift at play, away from this imbalance of greedy assholes getting their say while oppressing the poor. We see blatant failings on Wall St., in gov'ts across the planet; basically everything which is built on deception and power plays is blatantly showing it's cracks. Furthermore, as information becomes more free there will be more disruption of the tyrannical status quo.
The trick to winning the game is changing the rules. "The Man" has set a very specific rulebook involving forced miseducation, life-sucking factory-style careers, and depressing retirements.
These rules are unnatural, and shouldn't be followed. My personal rulebook is entirely different from what they distribute to the masses, and as such I have an entirely different lifestyle than the typical person, one that is infinitely satisfying and joyous.
tl;dr: You're correct, but not about your position in the hierarchy. Find the thing that makes you powerful and you will gain control. Freedom is a choice.
