Explain Jean Jaques-Rousseau's idea of social stratification.

For Rousseau, social stratification is based on a
fundamental perception issue.  Rousseau believed that individuals possess two types of
love of self.  One type is called amour de soi and the other one is amour propre. The
former represents a love of oneself that is affirmative of one's state of being in the
world.  This love of self is one where individuals do not seek to compete with others,
and is one that reflects a "man in state of nature" element.  Rousseau contrasts this
with amour propre.  This type of love is predicated upon self love, but it is a love of
self that is contingent on how others see oneself.  Amour propre is never ending because
individuals no longer understand their own sense of self, but rather see themselves as
how others see them.  This helps to breed competition and rivalry within society and is
responsible for the stratification that exists between people.  For Rousseau, displays
of wealth and the sense of vulgarity that results from it does so because individuals
view themselves as how others view them, distorting their reality, preventing
solidarity, and creating stratification.  Individuals thereby need social stratification
as it is a reflection of status and privilege, key elements in amour propre.  For
Rousseau, social stratification and division can only be overcome when amour de soi is
evident in both politics and social order, eliminating the presence of amour
propre.
