There's actually an anti-adoption movement in the US. (

In popular culture, I think of how the teen couple (Catelynn Lowell & Tyler Baltierra) who gave up their baby for adoption on MTV's documentary/reality show 16 & Pregnant and Teen Mom were treated by Catelynn's mom & Tyler's dad (who both have addiction & LE problems). They did not support the couple's choice to place the baby with a couple with the income, maturity, and stability to raise the child (which Catelynn & Tyler couldn't provide as teens and weren't given by their own families). They brought it up & threw it in their faces over & over again that Catelynn especially couldn't handle being a mom, didn't want the baby (so far from the truth- she wanted BETTER for the baby than what she could give her), had given her baby to strangers, etc.
I also think of the movie "Precious," (which is obviously based on fiction) in which the grandmother tells the poor, uneducated teen mom in an abusive home something like "only animals give their babies to other people to raise."
My perception (which could be completely off-base) is that the anti-placing a child for adoption sentiment is much higher among the poor and uneducated/undereducated in our society, although it is obviously not limited to this group (think of how Cindy Anthony - who is middle class- allegedly didn't want Casey placing Caylee for adoption).
There seems to be a cultural movement in the US towards keeping kids even when you don't want them or cannot care for them because there's a perception that placing a child for adoption for is bad, makes you less of a person, etc. I think many Americans, particularly those who aren't raised in the best of circumstances or have access to education (particularly about adoption), are taught by their socio-economic group that placing a child for adoption is selfish & wrong, when in fact it is SELFLESS & the right thing to do if all you are going to do is abuse or neglect the child like Dontrell's family did.
I don't know how we get this stereotype that placing children for adoption is bad or selfish to go away, but perhaps if we did, so many abused & neglected children would be placed for adoption because there wouldn't be a social stigma attached to it by their socio-economic group & family/friends. How many Dontrells would be alive?
And of course, the way to never have to deal with these issues if you don't want kids is to use all the available contraception methods (for men & women) that we are lucky enough to have access to in the US.
