I don’t why nobody mentions that raising kids and looking after the house is also a very important full time job, much harder than a standard 9-5.
If I ever got got married, and my wife decided to stay and look after the home, I will be extremely grateful to her as her contribution would have been far greater than mine will ever be.
However in case if she decides to work, which would be totally her own decision, then the equation might be a bit different. If she works part time and makes a small amount of money compared to me for reasons like her career progression, personal satisfaction or just as a time pass, then I do not think I will be comfortable taking any money from her. On the other hand if she has a high paying job which is demanding and takes up most if not all of her time then I might expect her to contribute something towards day-to-day running of the house as the expenses will definitely go up.
