> Daycares in the USA get away with it,

With a policy of hiring only women, or with being a field of mostly female solo operators without employees, with nearly 100% of applicants for places that do hire employees being female?

Because the two things aren't equivalent in the law.

By hiring only women as a policy. People overlook it, and a lot of parents don't want their children changed by a man. Plus, insurance companies mysteriously raise rates when men are on staff. My college friend started a daycare for his church and encountered all this fun, and I had to deal with some of these issues when we were running daycares (excuse me, Early Childhood Education centers) in the 90's.

I would imagine after rejection after rejection men would find something else (insurance was my friends out). It still amazes me how many industries insurance companies seem to influence the hiring in.

Do the insurance companies ask about the gender of a daycares staff?

The one my friend dealt with got a list so they could do their own background check, plus it was pretty obvious to the rep it was a guy asking for the quote this time as opposed to the first quote.

You may consider it "improper", but actually young boys are provided with plenty of role models, they just happen to be female.

If you reverse the sexes in your response then there would be outrage. Boys need to see men interacting with men and women to pick up on the social cues.
