that is an extremely macro level of culture that does not explain why there are so few women, hispanics, and african-americans in technology. They aren't that different of a culture. Certainly far less of a cultural difference than all of the H1Bs they're hiring.

You're not getting the point. All of you who keep parroting your master's "cultural fit" line are not seeing the lie for what it is worth. It's not about culture.
