Chance/Morals/Aristotle

Today in class we examined the notion of moral luck. The basic premise explains that all our circumstances are due to chance.  We cannot owe our situations to higher powers, self will, or determination.  The cycle begins when we are born- the parents we have and their particular beliefs and experiences directly affects our personality.  Due to complete chance each individual has a probability equally weighted.  This continues throughout our lives in which we become victors or victims to our circumstances.  If this belief is true, the basis that eternal realms exist to guide our bodies to the Good is invalid. Aristotle recognized that moderate wealth, good social standing, personal upkeep, and cultural awareness are directly linked to attaining reason and discovering the good.  If chance dictated all facets of our lives, would it be possible for any person to progress towards intellect, reason, moral actions, and the ultimate good? Personally I find moral luck would be a hindrance to self improvement based on these questions.  I know Aristotle did not specifically deconstruct moral luck and correlate it into his theory of human nature- I was toying with a concept we examined and attempted to integrate it into his theories.
