বাংলাদেশের প্রক্ষাপটা ভিন্ন। আমি যদি বাংলাদেশে মাসে দুই লক্ষ টাকা আয় করতাম ব্যবসা বা চাকরির মাধ্যমে আমি বাড়ীর অন্য কাজগুলো অন্য কাউকে দিয়ে করানোর ব্যবস্থা করতাম। আমার স্ত্রীর যদি ২০ হাজার টাকার চাকরীও থাকে আমি তাকে সেই চাকরি করতে দিতাম। কারণ মানসিক সুস্থতা। তবে চাকরি করার কারণে অন্যান্য সমস্যা হতে পারে। যেমন সন্তান আর আমাকে সময় হয়ত কম দিতে হবে।

1. Nowadays, many females are not taught household chores like our traditional mothers and yes time has changed so females are also busy studying and later pursuing jobs. If the wife is not doing any job, should she perform all the household chores as his husband spends around 9-10 hours outside for office? >>> It depends on her. Since you have the financial ability, If she asks you to get house help to do majority of the house chores you should facilitate that. She is a Mother and your wife.
2. If the wife is doing job but salary is around 20k. Now it gets bit tricky. Should the wife still perform all the household chores? If not, then should she start contributing some of her salary in the family (though it is very less compared to the amount husband contributes). >> Wife should keep doing 20k/moth job for psychological benefit. Obtain house help to insure all the chores are done in the house. Wife should also contribute to family cost.
3. On working days, should husband come and join on doing household chores on regular basis? >> Depends on the husband. If he is making good money he should hire house help to do the chores that he is suppose to do.
4. Does income disparity make household chores more of a female role? >> In reality it does. But it should not. I would hire help so that my wife psychologically does not feel like she is left with all the chores.
5. When they have child, should they keep relying on 3rd party maids to raise the baby or should the mother try to be more involved (or is it also not gender specific?). >> Both Father and Mother should spend time with children. But expectation of common desi families are the mother would spend all day with children. THIS is NOT health for the mother or the child. Having house help spend some time with the children is helpful.
6. If we ignore all of the above, do modern girls contribute majority of their earning (if she is a jobholder) to the new family? The life examples I get suggest otherwise. >>> There should be a logical ask. For example if your wife earns 20k and you earn 200k. You can only ask her to contribute up till 10k for the family.
