As a member of the human species, I'd like to think we've evolved far enough that we can live by the words...
"Article I. All men are born free and equal, and have certain natural, essential, and unalienable rights; among which may be reckoned the right of enjoying and defending their lives and liberties; that of acquiring, possessing, and protecting property; in fine, that of seeking and obtaining their safety and happiness." ~ John Adams
...or if you prefer this version...
"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the Pursuit of Happiness. That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed." ~ Thomas Jefferson
...or this version...
"I have a dream that one day this nation will rise up and live out the true meaning of its creed: 'We hold these truths to be self-evident: that all men are created equal." ~ Martin Luther King, Jr.
...or this version...
"We hold these truths to be self-evident, that all men and women are created equal." ~ Elizabeth Cady Stanton
...or this, and my personal favorite version...
"Nature hath made men so equal in the faculties of body and mind as that, though there be found one man sometimes manifestly stronger in body or of quicker mind than another, yet when all is reckoned together the difference between man and man is not so considerable as that one man can thereupon claim to himself any benefit to which another may not pretend as well as he. For as to the strength of body, the weakest has strength enough to kill the strongest, either by secret machination or by confederacy with others that are in the same danger with himself. And as to the faculties of the mind, setting aside the arts grounded upon words, and especially that skill of proceeding upon general and infallible rules, called science, which very few have and but in few things, as being not a native faculty born with us, nor attained, as prudence, while we look after somewhat else, I find yet a greater equality amongst men than that of strength. For prudence is but experience, which equal time equally bestows on all men in those things they equally apply themselves unto." ~ Thomas Hobbes
...now what is the name of the groups/political persuasions that famously hate the concept of equality again?
We all breath the same air, drink the same water, eat the same food, we all shit, we're all born and will all die. At what point is the fine line between needs and desire crossed, and who gets affected the most negatively?
Ever notice that most casualties in war, draught, famine and disaster are poor people? Most of us live in the trenches of class warfare.
I couldn't possibly agree more with poly and arkay nor could I express it more eloquently. It's good to see that there are people who have a higher sense of moral standards.

(and you don't have to be a religious person to get this basic concept that seems so alien to so many people)
Nobody should ever have to suffer because of another persons desire to have more an they need.
