Using specific examples from Kozol's essay, how is independence and choice related to literacy?

Kozol makes the argument that individuals have choices
when they are able to read.  For example, consider the Campbell's soup can labels to
which  Kozol alludes.  He argues that because they all look fundamentally alike, it is
near impossible for someone who is illiterate to really understand what they are eating
or what they choose to purchase.  Accordingly, those who are illiterate are depending on
the pictures on boxes or labels to help guide them, indicating a lack of choice because
of illiteracy.  This spills over into the realm of children.  Someone who is illiterate
cannot understand the letters that come home from schools and teachers.  The illiterate
parent cannot understand "the SAT Prep classes" that are being offered, courses that
open doors to children for college and higher education.  This is another example of how
Kozol argues that illiteracy removes the issue of independence and choice.  Finally, the
issue of driving and navigating street signs and instructions are related to the issue
of independence and choice.  The 48 year old man to conclude the article whose car broke
down, but could not tell the police officer where he was because he could not read a
street sign reflects how independence is minimized because of his illiteracy. All he
could say was that he was "on a one way street."  There is no better image to reflect
the dependence and lack of choice in the existence of someone who is illiterate than
this one.
