Let us face the fact upfront, if you earn average money and have princpled attitude towards the institution of marriage, so you donot even mention a word about money/ dowry, your inlaws may give their daughter dowry or may not give her any dowry because of practical monetry problems but your life is doomed if your wife's wants are not fulfilled in future for want of money. She will curse u endlessly for not earning enough to meet her demands for decent home with all facilities thrown in. You will be trotured mentally regularly day in day out, because she will hold you responsible for all her woes because u didnot say no for the marriage, if you had refused she could have been married in some rich household. Moral of this write up is that if u demand dowry the law catches up with u for a crime of demanding dowry and if you don't than your wife will kill you everyday and you exist in this world like survivor till death embraces you.
