In some men they see themselves as the family provider, and dislike the thought of a wife bringing home her own income, it's the old fashioned idea of the Hunter gathered role whilst she stays home to raise strong healthy children. My own Grandfather was like that, born during Victorian times, it was simply not the done thing for a woman to work, and young girls were expected to give up their job and become stay at home house wives the day they got Married!
This sometimes went a step further, with only Sons allowed to inherit their Fathers estate, not Daughters, and to this day, it's common to see a Company listed as ' John Smith &Son' but very rare to find one registered as 'John Smith and Daughter'!
If a Man only had Daughters, it often fell on his Male siblings to inherit his fortunes, or even a Son-in-Law if he had worked in and help to develop a partnership in the family business.
Thankfully the Laws have now changed and Daughers have equil rights in inheritance to their brothers, but my own husband disliked the fact that my inheritance from my father was for a greater amount than he had inherited from his Dad over 20 years ago!
