The only legitimate concern I feel is one that she never even raised - with a finite limit on places in tertiary education, a person who gains tertiary qualifications and then does not utilise those qualifications in the workforce (whether on a temporary or permanent basis) may leave a shortfall. I could see this being of particular impact on, for example, the already stretched medical industry, where educational places are not sufficient to stock the demand in the workforce.

In general, it would be interesting to see the total number of university graduates who do not utilise their qualifications in the workforce, compared to the number of women who do so in order to raise a family.
