Help me out. Here is the CCC on a just wage:
2434 A just wage is the legitimate fruit of work. To refuse or withhold it can be a grave injustice. In determining fair pay both the needs and the contributions of each person must be taken into account. “Remuneration for work should guarantee man the opportunity to provide a dignified livelihood for himself and his family on the material, social, cultural and spiritual level, taking into account the role and the productivity of each, the state of the business, and the common good.” Agreement between the parties is not sufficient to justify morally the amount to be received in wages.
I see you referencing “needs” of the person, but not the “contributions”, “the role and productivity”, “the state of the business”, and “the common good”.
So a hypothetical for me to better understand your position. Lets say I own a small burger stand and I have two employees to flip burgers: one is a high school kid and the other a father of 10. Am I to pay the father of 10, approximately 10 times more than the high school kid? (or whatever is required to support a family of 12).
