Interesting. But if every couple starts thinking the way Freedom2012 and gyanguru did, there will be  no baby/kid left in the world to be adopted. That means couple who can not have a baby of their own for some physiologican reasons but love to raise a kid very much will have difficulty finding a baby to adopt. So, theoretically it will not work and people will be forcefully driprived of fatherhood and motherhood.:)

In Nepal and even in developed countries i come across the statement like : One of the causes of underdevelopment is overpopulation. And over population is due to many reasons, among which, one is mentioned as: "Because in a life of low material gratification , raising children is among the few joys and delights one can have in underdeveloped countries". Some even say, because of less access to recreational facitlites people are more involved in 'love making' as a substitute. This may be true to some extent :). Nepal ma Load shedding ko asar dherai bachha janminchan re, yo gaf nai ho ki kasaile research gareko ho thaha chaina :) BUT the former reason of " material gratification low bhayera teslai joys that comes from raising a child le substitue garne" is ridiculous. Saying in Economists' way : utility you get from raising a photocopy of yourself is not achievable by any mateiral commodity for many people.
