I personally don't want to have a kid of my own blood. But I want to adopt one or two and maybe foster a few IF I become financially capable, which is probably a decade or so away.

I do believe that having a kid of your own in this day and age (esp. when you are working day job and depending on that job for healthcare, housing, etc.) is unfair for the kid who will join you in your life. Sure you'll love him/her, but the reality is the kid will have to grind (again, assuming that you are not a multi-millionaire) when s/he reaches certain age. The best use of our resources, when we accumulate a good amount of wealth to sustain ourselves and have a bit more extra to spare, is to adopt/foster or do something philanthropic entirely (so many homeless, sick, hungry people that you can help).
