men and women were both given the same choice of universities and classes in high school. the tech sector did not turn its back on women or minorities, they turned their back on it. now that its profitable they want a piece of that pie.
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?
Its actually not really an anomaly for jobs that pay fairly poorly and confer little power or respect to be dominated by women and/or persistently disadvantaged minorities. (It's really part of the same effect as jobs that pay well and confer power and respect being dominated by white men.)
none of which get neither money nor respect.
But this is hacker news. A site for people in the tech industry, not the childcare industry. We can and should care about representation and participation and opportunity in our industry. We can do something about it here.
Why do you think women feel the need to create websites like this (https://mixpanel.com/i-am-tech/) in the first place if the idea of being a woman in tech is only "historically" eyebrow-raising?
The assumption that sexism is, like racism, one of those things that people used to do in the 1950s, is really not helpful.
Look at the graduation rates for women and minorities from CS programs; then look at the industry participation rates, particularly over time and particularly with reference to seniority. They're not turning their back on tech, they're being driven out.
Don't lie. A simple websearch returns very many hits for people talking about the shortage of men in pre-school and primary school education.
