while i may agree that communism/socialism in pure form is a novel
idea, it is pretty much against human nature.  greed is part of human
nature, it is something we are all guilty of, i'm sure you've heard of
"keeping up with the Joneses" and that is the way it is, yes there are
doctors who join the practice in order to help other and better
society, but because of it's monetary rewards it pulls the best and the
brightest into the field.  because of the great incentives, people who
have the greatest skill in regards to that particular field are
generally the one's who make it.  now if there was not such a great
monetary reward, would as many of these "best of the best" even make an
attempt to pursue that career field? simple answer is no.  the problem
is that utilitarianism is based on  ideal principles which are good
thoughts, but just do not play out in real life, thus leaving the
capitalist format as the best remaining option. However, look at
current countries who are practicing or were practicing some form of
socialism, now why is it that people were leaving those countries in
flocks? why do so many cubans defect to the united states? simple
reason, people want more for themselves, they want that house in the
suburbs with a mercedes in the garage and a massive plasma screen tv in
the living room.  it is the middle class that usually pushes for more,
not the lower or upper class, but the middle class, why? because they
potentially have the greatest work ethic, and see making it to the
upper class as tangible. yes capitalism is corrupt, but every single
communist government has been as well, thus proving the point of human
greed. which defeats socialism and communism at it's core. however, i
will never agree, and i'm sure you will not either that a man flipping
burgers at mcdonalds deserves the same wage and benefits as a man who
saves people's lives
