Yes, it does. The number that matters is number of available black and hispanic tech workers versus the number of employed black and hispanic tech workers. If there was a large discrepancy between unemployment rates for technology workers along racial lines, then we could claim discrimination by companies.

Instead, what you and this article are talking about is that perhaps not enough black and hispanic people are being exposed to technology as an industry. In which case, the failure would be on a lot of variables: community, family, schools, socioeconomic status, etc.

Blaming a company for not hiring non-existent people is sure great for Jesse Jackson's business model, though.
