Just living life requires basic algebraic skills. Loans, insurance, taxes, and virtually any kind of projection into the future require concepts like X = 2Y. Understanding that something is linear or exponential is critical to and to understand when one is better than the other requires that someone learn how we as society express those concepts, which is algebra.

The person who can't read can be a traffic guard, server (with the right cash register), bricklayer, or any of a number of jobs. However, all of those people need to know that they worked X hours @ $15/hour and should be paid 15X. Otherwise they will never know if they were ripped off or be able to plan for the future.
