Yes, and? For example, best programmers are overwhelmingly white and male, because majority of programmers are white and male. (Not sure about race, but it's probably true in Western countries). The majority of people interested in founding technology startups are probably white and male, and therefore the best people for starting a technology startup are white and male. You comment implies that it's wrong to state that the best people are overwhelmingly white and male, if you don't imply that, please make it clear.
If women are as skilled as men in, say, programming, then majority of best programmers are male.
>2. The VC ecosystem has some pretty systemic biases and prejudices (this is not to say that startup people or programmers or anyone is particularly evil; in fact, almost everything has systemic biases and prejudices), and as a result the current landscape does not reflect the best possible set of founders, startups, and opportunities.
There's a third possibility: women and non-whites in Western countries are less interested in applying for venture capital. If that is the case, then in an equal world venture capitalists should invest less in startups founded by non-white women, because the majority of startups seeking venture capital are founded by white males.
The overall point is that you need to fix the root cause, not the effects of the cause. As long as women and non-whites are minorities in groups of people such as tech students, you should see less women and non-whites in tech student related phenomenon, such as technology startups.
This reminds me of all these communities like "AngularJS women", who try to get more women into AngularJS. I think that's pointless. Once 50% of software engineers are women, and once women have exactly the same interests and values and beliefs as men, you'll find that 50% of AngularJS developers will be female.
