One economic theory that could relate to this letter is the classical economic theory. This
relates because the information that was stolen by the hackers was probably stolen for
monetary gain because they can sell your private valuable information. Another economic
theory that could relate is the Laissez-faire economic theory, because this company is for the
most part not controlled by the government.
One social theory that could apply here is the social theory of perceived risk. Now that
someone has been hacked like this they may not want to do business with this company again
and or be more careful with where they put their information now. Another social theory is the
belief that criminals primarily are motivated by financial gain as it appears the data was most
likely stolen for this reason.
