Altruism and selflessness in any form are always good things. I also donate to things which help kids in their health and education. Perhaps you can donate more as you do not have your own. But, if you portray the people who have their own child as selfish as opposed to those who adopt or who do not raise a kid at all, it sounds not so right. Man by nature is a selfish creature. For many people the satisfaction they get by raising a child is never comparable with what can do to make 'mother earth' a better place instead by donating the wealth to raise kids who are in need. I have met couple of people who are not being able to bear a baby, they are well educated and it seems they understand the happiness a orphan child gets if they adopt one. Instead of doing this, they  desperately need a baby of their own. And they are even ready to donate all the wealth to a charity if someone can help them on this. NOt all the people are that desperate, but eveyone has some portion of selfishness.   Actually my objection was towards the generic statement of "raising child in underdeveloped countries substitues the material gratification which they can not afford".
