The characters in any allegorical story are often used to symbolise certain concepts. These may be types of people (stereotypes); a group or organisation; a part of the mind; a power or force; etc.
 
Below are a list of the main characters in the film and what they symbolise.

Mr. Rhineheart (Neo’s boss)

A typical company man for whom the company is everything. A heirophant who wields his authority with impunity to maintain the pecking order and protect his position in it.

With a bureaucratic mind, his job is to enforce company policy without question. He has no care for the employees under his command, regardless of their abilities.
