You're right, the "tech tribe" does have improvements to make in inclusivity, but at least it's a home for some people who would otherwise be outcasts in socially conservative businesses.
As for a few things:
- I think we're just as accepting of blacks, our high school education system has just utterly failed them so much that we don't have a good pipeline for getting black people into tech.
- There are a different set of values in India that cause some clash between them and Americans/Westerns. There's the culture of following the letter of the request/task, rather than the spirit of the request/task. (Similarly but differently, mainland Chinese suck at asking questions when they don't understand something.) But my overall biggest complaints with outsourced contractors is a culture of "get shit done fast, and do any hacks to get it done". Because contractors don't stay with projects for the long-term, it's not surprising.
- The homeless and lower class are, almost by definition, not people who are achieving a ton. Tech is a meritocracy, we respect getting shit done, and we're not a jobs program.
