As abortions are outlawed more and more, expect this to continue.
As for adoption, take the amount of abortions and child deaths/abuse per year and assume 18 years of care for each year of kids. Last time I did the calculations it equalled a mid size city of kids that would require massive infrastructure investment.
Some people shouldn't have kids, and it's definitely the kids that suffer that the most.
Now I'm not saying what the solution is. Just that this is the result of our current domestic policies.
