If I'm the primary breadwinner of the family, then it shouldn't be too hard to ask for a clean home to come back to every evening. However, I do understand that my wife may not always be able to keep up with her chores, which in that case I shouldn't mind helping her out every now and then.
If we both work, then we both should equally contribute to the household chores.
If she's somehow the breadwinner, then the household chores would be my responsibility.
It's really not that hard of a concept to grasp; everyone has their fair share of work to complete and distributing it to make it simple for both the husband and wife should not be seen as that big of a challenge.
