Blind day care supervisors
I am a firm believer in the free market, but there is also a role for the government to protect those who are not able to protect themselves, such as children. Personally, I think it is risky for the state to license two blind people to run a day care. Risky for the children, first of all. Also risky, from a liability standpoint, for the state.
As is mentioned in the comments at RWN, children who are raised by blind parents are special. They understand their parents' limitations and are taught how to work with these parents.
However, 4 or 5 year old kids who have never been around blind caretakers are going to be too much for them, IMHO.
Perhaps this daycare can cater to the children of blind parents.
