Eric's question, “why shouldn’t they try for the highest wages,” underscores his belief in the fundamental fairness of workers seeking better pay. It reflects his desire for a more just and equal society, where employees are paid a fair wage for their labor.

Eric challenges the status quo by questioning why workers should settle for less than what they deserve
