The same tortured analysis plays out in the business world, where Paul Graham, the head of YCombinator, a startup incubator, explained that one reason his company funds fewer women-led companies is because fewer of them fit this profile of a successful founder:

If someone was going to be really good at programming they would have found it on their own. Then if you go look at the bios of successful founders this is invariably the case, they were all hacking on computers at age 13.

The trouble is, successful founders don’t run through a pure meritocracy, either. They’re supported, mentored, and funded when they’re chosen by venture capitalists like Graham. And, if everyone is working on the same model of “good founders started at 13″ then a lot of clever ideas, created by people of either gender, might get left on the table.

A similar argument was presented in an article at Slate: Affirmative action doesn’t work. It never did. It’s time for a new solution.:

But even if the government were keeping better tabs on affirmative action, the bigger problem is that its jurisdiction doesn’t reach the parts of the economy where affirmative action is most desperately needed: the places where real money is made and real power is allocated. The best example of this is the industry that dominates so much of our economy today: the technology sector. Silicon Valley’s racial diversity is pretty terrible, the kind of gross imbalance that inspires special reports on CNN.

It’s a dismal state of affairs, but how could it really be otherwise? Silicon Valley isn’t just an industry; it’s a social and cultural ecosystem that grew out of a very specific social and cultural setting: mostly West Coast, upper-middle-class white guys who liked to tinker with motherboards and microchips. If you were around that culture, you became a part of it. If you weren’t, you didn’t. And because of the social segregation that pervades our society, very few black people were around to be a part of it.

Some would purport to remedy this by fixing the tech industry job pipeline: more STEM graduates, more minority internships and boot camps, etc. And that will get you changes here and there, at the margins, but it doesn’t get at the real problem. The big success stories of the Internet age—Instagram, YouTube, Twitter—all came about in similar ways: A couple of people had an idea, they got together with some of their friends, built something, called some other friends who knew some other friends who had access to friends with serious money, and then the thing took off and now we’re all using it and they’re all millionaires. The process is organic, somewhat accidental, and it moves really, really fast. And by the time those companies are big enough to worry about their “diversity,” the ground-floor opportunities have already been spoken for
