With cases of failed marriages and an increasing population of youths without proper training and upbringing, it's sad to know that the root cause of it is mainly as a result of poor financial structure and plan before entering into marriage.
In as much as I agree with you in some areas, I will also point out to you that financial stability is not the only ingredient for a happy and successful marriage. Although, it is an important one because financial problems are one of the leading causes of divorce recently actually. When couples don't have a stable financial situation, it can lead to conflict and stress, which can ultimately take a toll on the relationship. However, we have seen cases of divorce even with the richest people and definitely it can't be financial issues that caused the divorce. My point is, a marriage destined to fail must surely failed no matter how financially buoyant they are. Marriage is all about understanding and trust and believe me, if these two are present in any marriage, finance will likely not cause harm to such marriage as long as they can feed.
You have pointed out a good thing. However, there is no place i see were the OP made mentioned of being excessively rich before going into marriage. In my understanding there is no specific age, level of finances before a person can go into marriage. All is needed is to be financial stable, in such a way that the main responsibilities are being responded to. Such things include shelter, food, electricity, water supply and other essential life needs. Once all of these are settled without stress then starting up a family will not be an issue as the basic things of life are available.
If I may ask you, what do you understand by financial stability? Having financial stability has no much difference from being rich.
From the example you mentioned, food, electricity, water, shelter and other essential life needs, tell me what else you need again. These are what the riches possess and you can not wait to have all this before you think of settling down and start a family. You know some people financial breakthrough starts after marriage.. Financial stability is different from stable income and what matters here is stable income. The Bible that Op use as the reference also stated that a man need helper in his life which referring to wife. Your wife might play important role to your financial breakthrough and freedom.
One needs to have proper financial planning of course but that shouldn't hinder you from taking a partner if you have the means. You and your partner can build your home together with the support of one another. The success of your home depends on how well you can manage it and not how wealthy you are.
