Most threads have a mixture of comments, some nice and informative, others superficial, and even stupid. I see three comment son this thread, and I have not merited reading something rational and respectable.
Firstly, marriage is something that is dear and precious, a huge portion of the continuity of Klal Yisroel, and a truly holy mission. The Torah also tells us about the failed marriage, with the parsha of gittin. The surrounding issues of marriage, finances, the circumstances of the family, etc. are all potential sources of challenge and conflict, as well as potential sources of great joy, simcha, and nachas. Marriage creates the completion of the individual. All this stuff is plentiful in seforim, and I do not need to copy and paste anything here. We can all find the material.
As for the income, it is not an unimportant issue, but it is a secondary one. Many of us may know someone who was wealthy, but in an unhappy marriage. Gehinom on earth. We might also know someone who has a difficult financial situation, but has a happy family. Who would you rather socialize with? Who would you rather be?
Lastly, the wife’s salary belongs to the husband. There is some truth to this statement. But there is more myth to the way things are portrayed by that statement. This depends on much, it is a takonas Chachomim, but within a context of other takanos. When the “salary belongs to the husband” issue gets raised, there is a troublesome situation going on, and being small-minded enough to deal with that without addressing the need for a couple to live in peace, harmony, and affection, is a disservice. I have observed countless people who consult with non-professionals (such as the overwhelming majority of well-intentioned rabbonim) only to get piskei halacha thrown at them. This is a huge problem that contributes handsomely to the scourge of gittin. Once we enter the divisive approach of “this is mine, not yours”, we feed the barriers between a husband and wife. You cannot call this shalom bayis. It certainly defies the great virtue we speak of every morning when we list ??? ????? ???? ???? ???????? ????? ??? ????? ????? ?? ????? ???, when we list ???? ???? ??? ??? ?????. Getting into the mode of “You’re right”, is one of the ingredients of the problem. Am I the only one that recognizes the stupidity of just doing more of the conflict that divides them?
The place we need to be with the financial issues of a couple is, “We have financial burdens that we need to resolve,” not me against you.
