Negative impact of any fixed number of children norm

Parents are human beings. Though we leave no stone unturned in projecting them as selfless service providers to their children they are not any such types. Some of them love to have children only to adore them as because they are affectionate adults. Some of them fix priority on the satisfaction of sexual urge without any hindrance to be considered as family planning. Children born to those parents are no more than byproducts of sexual intercourse. Any method of contraception is most unwelcoming to this type of parents. They don't do any calculation of how much money they earn and how much money they need to nurture those little human byproducts of their sexual intercourse. Moreover they think among so many children born to them there would definitely be sufficient number of sons who would serve them in their old age. These sets of parents would definitely unlawfully test the gender of the children in womb and definitely abort female foetus to get rid of the cost of marrying off their girl children. Moreover married men and their families would compel their wives to face and bear with the trauma of frequent abortion of girl foetuses. Northern and Northwestern India is under the the strong grip of this regressive, torturous son-prefering patriarchal mindset. So as a citizen of India I'd prefer to widen the base of opportunities for girl children to establish themselves into educated working earning persons through the long years of upbringing. And some special extra financial benefits and support system for parents of girls as only children.
