If only one of them earns a salary, and it is agreed upon by both, why is it unfair? That’s a perfectly valid choice - not everyone is a careerist and if one salary is enough for the family it is a really healthy choice. This “life is about work mentality” is honestly, harmful.
Doing chores at home is no less hard than working at office, and much more thankless activity. Both me and my wife much prefer to do anything else than domestic labor, including actual work. So, it is quite unfair to ask only one of us to do all this.
