Yes, it is absolutely okay for a husband to allow his wife to work, even if he can afford the expenses of the family by himself. In modern societies, it is generally recognized that both partners in a marriage should have the freedom to make their own choices about their careers and personal lives, regardless of their financial situation.
Encouraging a spouse to pursue their career aspirations and goals can lead to a more fulfilling and balanced life for both partners. It also allows for financial independence, personal growth, and a sense of accomplishment for the working spouse. Moreover, having dual incomes can provide financial security and flexibility for the family, allowing them to achieve their dreams and plan for the future more effectively.
Ultimately, the decision about whether or not the wife should work should be based on the couple's mutual understanding, communication, and respect for each other's choices and aspirations. It's important for partners to discuss their expectations and preferences openly, so they can reach a decision that is suitable for both of them and their family.
