If you marry for money you will earn every penny.

The line warns against treating marriage as a financial transaction. It suggests that marrying primarily for wealth carries hidden costs: emotional labor, loss of autonomy, resentment, and the ongoing effort required to maintain a relationship built on material incentives rather than mutual respect and affection. “Earn every penny” flips the usual idea of easy money into a moral and psychological bill that comes due over time—implying that the spouse who marries for money may pay through unhappiness, compromised values, or a power imbalance. In a broader sense, it critiques instrumental relationships and argues that choices made for short-term gain can create long-term obligations that feel like work.
