Probably not. The difference is that we can do things to prepare foster parents or adoptive parents for it - more so than natural birth.
And to be fair, you aren't "fixing" a baby: You are doing the same thing - providing a loving home, trying to give another person the things they need. You just have a head start on some of the problems you'll be facing with a teenager - the sort of thing that blindsides parents of babies if it happens.
I'm not sure why it is an issue that "things are hard".
I think that you should look up what trauma and dysfunctional early setup does with kids. Because it can be very hard on caregiver and test all their abilities including self control. The adoption agencies themselves are quite open about these issues - they do not want people to adopt and then be unable to handle things.
Which are all euphemisms mind you. Basically, there are issues with violence, inability to create relationship or even inability that relationship can be "true". Which causes whole other bunch of behavioral problems. Like, the eagerness to "test" caregiver by really going out of way to create trouble. And if caregiver fails, result is basically abuse. And the kid can't help itself, but adults should.
And adults when they see they don't have time and resources and patience to deal with above, do better to adopt baby.

What did that even means?
