Oh, sorry if that wasn't clear. Foster children here aren't up for adoption, only in very rare cases. The two systems are for different purposes. The foster children typically have needs that require foster parents with special training. Often the foster children still have some contact with their biological parents, so again, specifically not up for adoption. Adopting is difficult, you'd have more success as a foster parent, but it's harder to be approved as a foster family, e.g. you need special training.

I get that systems are different around the world, but solutions like this is still required or at least wanted in countries where adoption is pretty much not an option. It is a pretty fortunate situation to have a society where adoption is so rarely needed, but it's also massively hurtful to would be parents to suggest that they should simply adopt, when they want to, but does have that option.
