What are some examples of social sins in "The Blind Side?"

I think that there are many examples of social sins in the
film.  On one hand, I think that there is a fundamental social sin in the idea of
children being abandoned by their parents.  Michael's mother being held in the grips of
drugs can also be seen as a social sin, one that forces parents to abandon their
children.  At the same time, the fact that Michael has been bounded around in the foster
care system for a prolonged period of time can be seen as another social sin.  It would
seem that someone who has been in the system as long as Michael would have awoken the
concern of some member of the system in order to see to it that Michael's voice is heard
and his needs are met.  On a larger level, I think that it is a social sin that Michael
only experiences good fortune because he plays football.  It is conceivable that Michael
would not have had such the positive fortune he had if he were a nuclear science
student, or one who was able to compose free verse poetry, he would not have been able
to obtain a full ride scholarship to a Division I school.  It might be seen as a social
sin that athletics is so highly valued, a system where young men and women are seen as
means to an end and not an end in of themselves.  While these student- athletes benefit,
they are not entirely being treated with entire respect and this could be considered a
social sin.  Again, this is not to denigrate his own story, as what happens to Michael
is heartwarming and personally redemptive.  Yet, the inordinate emphasis on athletics in
the country can be seen as a social sin, especially when seen at coming at a cost of
other endeavors.
