How do orphanages work in the United States? Do they still exist?

Question

I'm curious how American orphanages work and what kind of treatment the children go through.

Answer 1

not that I am aware of.  We have the foster care system, the juvie jail system, the handicapped shared housing, and an orphanage that used to exist in my town has been changed into a live in school, discipline  home for kids in need of supervision.  It would be very nice if none of these things were necessary, but I doubt if we will ever see that.

Answer 2

The overburdened foster care system is a replacement to orphanages.

Answer 3

I know there was one in San Antonio.  

I honestly do not know how that works. . .  I know that sometimes, there's not enough foster homes to go around.
