Why is it that the law requires people to take parenting classes before they become a foster parent, but..
When a couple is expecting a biological child, the law doesn’t require them to take any classes.

That sounds one-sided to me; shouldn’t all soon-to-be-parents be held to the same standards?
Why are temporary parents required to do stuff that permanent parents dont have to do?
I would think that permanent parents should have higher standards.
Why do the temporary parents have higher standards?
