both working - problem or not?

Is it an ego problem for men, when their wives are independant and self-sufficient?
I had a conversation with a good friend of mine about her hubby, who was complaining that she refused to take money from him, because he felt that she wanted to tell the world that she made it on her own, without his help.
For a start, I cannot understand where that idea came from.
If a woman is self-sustaining, doesn't that reflect that she obviously didn't marry for money? To make it worse, it's not that her husband has a bottomless bank account, he works like any average singaporean - and she has her own little 'business' which provides for her basic needs and sometimes a little more.
They had a huge argument about this and the lady is clearly upset.

If I were a man with a 6 digit income, then I probably couldn't care less if my wife wasn't contributing. BUT in our society today, most are not earning even 5 figures and having both working, does help to pay for vacations, odd lunch treats and little luxuries. There is nothing wrong with both helping to make a more comfortable life for each other - with more income, there will be a higher chance of putting some money aside as savings.

This couple has been married some 10-odd years - and for this to happen now is rather strange - because this has been the way they were before they married. It wasn't a new situation. What was the trigger?

In my opinion, being self-sufficient is the best way to go. BUT to make an issue of it after a decade is really beyond me. Perhaps then, the male ego had ideas to change the equation over time, and now that time has lapsed, and things are still the same, he is feeling inadequate.

Well, that is a personal deficiency and one should not blame the other person.
If we walked the wrong track and just find ourselves back to square one, then blaming the other person is not justified. We may plan a career path, yet get side-trackked along the way, never meeting our goal. Whose fault is that?

The bottom line is this: If we fail, then we should take a good hard look at where we went wrong.
When our spouse is contributing to the household, it's not a real problem.
It's a problem because the male ego cannot accept it's inability to fully provide.
