Hello, I want to add that some people possess qualities that make them more successful than others and which distinguish them from others. These qualities include things such as being intelligent or gifted, having athletic ability, beauty... This is one of the reasons why people are unequal.

Hi your quote comes from ' A Discourse on the Origin of Inequality Among Men 'by Jean Jacques Rousseau "I conceive that there are two kinds of inequality among the human species; one, which I call natural or physical, because it is established by nature, and consists in a difference of age, health, bodily strength, and the qualities of the mind or of the soul: and another, which may be called moral or political inequality, because it depends on a kind of convention, and is established, or at least authorised by the consent of men. This latter consists of the different privileges, which some men enjoy to the prejudice of others; such as that of being more rich, more honoured, more powerful or even in a position to exact obedience"

Hello Menevado, It is a great question! It is difficult to say the origin of inequality among people because there are many reasons like unemployment, lack of opportunities, economic situation, war, epidemic, malnutrition etc... It is a vast question...

A FAMOUS author, reckoning up the good and evil of human life, and comparing the aggregates, finds that our pains greatly exceed our pleasures: so that, all things considered, human life is not at all a valuable gift. This conclusion does not surprise me; for the writer drew all his arguments from man in civilisation. Had he gone back to the state of nature, his inquiries would clearly have had a different result, and man would have been seen to be subject to very few evils not of his own creation. It has indeed cost us not a little trouble to make ourselves as wretched as we are. When we consider, on the one hand, the immense labours of mankind, the many sciences brought to perfection, the arts invented, the powers employed, the deeps filled up, the mountains levelled, the rocks shattered, the rivers made navigable, the tracts of land cleared, the lakes emptied, the marshes drained, the enormous structures erected on land, and the teeming vessels that cover the sea; and, on the other hand, estimate with ever so little thought, the real advantages that have accrued from all these works to mankind, we cannot help being amazed at the vast disproportion there is between these things, and deploring the infatuation of man, which, to gratify his silly pride and vain self-admiration, induces him eagerly to pursue all the miseries he is capable of feeling, though beneficent nature had kindly placed them out of his way. if you want to continue reading this try to find this site below http://en.wikisource.org/wiki/Discourse_on_the_Origin_of_Inequality_Among_Men/Appendix cowboy...
