If the child care industry were representative of men's exclusion from most high paying, socially powerful fields, then I would expect the 'bitching' to begin. But, as it is, the child-care field is not a field that a lot of men would like to get into, it pays fairly poorly, (unfortunately) confers little power or respect, and is largely an anomaly in an economy where most jobs, especially powerful ones are dominated by men.
The "confers little power and respect" bit, by the way, seems to be true of most woman-dominated fields (child care, teaching, nursing...). Do you suppose this is a coincidence?
