@Mafialligator:
I'm not saying that any protest against corporate greed fails because of human nature.
To adress your whole post:
-When I say greed/self-interest is in our nature, I mean that in a more animalistic way...ie, it's not so much human nature as just *animal* nature, something that's inextricably linked to animals. All animals have a drive to survive, and THAT is wehre self-interest kicks in--obviousl, he or she with the most resources and best genes in any animal race has the best chance at winning mates, space, food, happiness, and the survival race. That being said, I'm NOT saying that human beings must never be above all animalistic tendencies, but I don't think you can make a case for this one being shaken off--it's not a drive towards excess so much as, again, survival in the most comfortable manner, and greed/self-interest is a means to that greater end, and a necessary means. What's more, it could be argued such a tendency is actually literally impossible to escape as its encoded in our very makeup, if "The Selfish Gene" argument is to be believed (and I buy it.)
-Locke said that human nature was something like a tabula rasa, a blank slate, and Sartre that it was human nature to NOT have a pre-set nature, but to create out own; both are true to an exent, but again, as long as human beings are animals--and unless we have something other/divine, ie, God, that sets Man above animals, we must take him to be an animal, albeit a very smart and highly-developed one with great potential--then they must follow the natural, biological laws of animals, and one suich rule is, again, "Survival of the Fittest/The Drive for Mates/Comfort," which is where greed and self-interest stem from.
After all, the caveman who first sparked fire likely did so be cause he was cold...the Sumerians who invented the wheel, language, and irrigation did so because it helped with trade and to grow, move, and sell more food and resources...inventors such as Edison worked for profit as well as progress...
And as much as aesthetes might have you believe otherwise...
Mozart Beethoven, Shakespeare, Plato, Dickens, Michaelangelo, Picasso--ALL worked/composed/wrote for money to get ahead in life.
It's at our core as animals to do so--we as human beings just refine the process more...instead of scavenging for food, we have a system of economics and trade...instead of mere calls and animalistic displays, we recite poetry or go out on terribly awkard dates worthy of sitcoms and have conversations and show wit--amongst other things--ot attract mates (those of us who date, anywho...) ;)
We're more highly-refined animals, but we ARE animals--and as such, we're driven by animalistic tendencies, which are fine, as these...well, these have helped us suvive for hundreds of thousands of years and continue to do so.
-I DO like the "become aware of our nature" bit as being part of human nature...that's a pretty Sartre/Camus-esque thought...
-Again, I haven't knocked all protests against greed--case in point, I supported Egypt's revolution, and that was about a greedy dictator and wanting more "fairness," at least on paper, in reality, it was somewhat different, but I digress.
-I also haven't supported all instances of greed...I'd have to disagree with such great figures as Bertrand Russell and one of my favorite authors, D.H. Lawrence, and say that the French Revolution WAS justified and was a good thing insofar as it was justified and what ULTIMATELY, in the LONG run, came from it...the short-term was pretty awful, what with the Reign of Terror and the restoration of the Monarchy; it's up to every individual to decide whether Napoleon was a good or bad move, I tend to lean towards it being slightly in the good, but again, it's open for debate (BUT NOT HERE, OH, GOD, NOT HERE, NOT ANOTHER 100+ POST DIGRESSION DUE TO A HISTORICAL WAR IN A THREAD!) :/
-If we take your last argument, your reasoning seems agaisnt itself--if we DO accept that human nature is inherently greedy, it seems absurd to think we'd need REMINDING of that...after all, most everything that is inherent to "human nature," ie, Survival of the Fittest, is pretty well known by people already as it's well, inherent...if not to ALL people, than certainly to most. It'd be pretty absurd to stage a demonstration explaining to people why drinking water is so important--it's sort of a given, we already know. We already know we're motivated by self-interest. Conversely, it'd be equally pointless to bang on in public about how getting sick is bad for your health--again, kind of a no-brainer. If we take Aristotle's Argument for Moderation and call "Greed" an "excess" of the "virtue" of "self-interest" (since, given all the good it produces, I think we can agree to it as being a virtue in the Greek sense of the term), it follows that, just as Aristotle argues an excess of anything, even a virtue, is bad for you, this seems analogous to telling people getting sick is bad for your health--it goes without saying.
