It sounds more like the relatives raised the both of them. It’s good that the family raised him, however I am opposed to special programs which permit mentally disabled people to marry and have children while the state subsidizes the whole matter down to the apartment and social worker who helps the child with it’s homework, etc.
In my opinion having children is not a right and those who can be responsible are the ones who should ahve children. I know I will be accused of promoting eugenics perhaps I am.
I also believe programs which pay drug addicts(who have previously given birth to drug addicted babies) to stay on birth control sound as well.
