In reality, 70% of Indian civil and military institutions are dominated by upper castes. The plan is to reduce that to 5% or so.
I hate to say it, but our IT department IN THE UNITED STATES appears to be suffering the effects of the caste system.
Our Indian IT director (now a US citizen) has routinely replaced well-qualified Indian technicians with members of his own caste (confirmed) and people from his own region/state (confirmed). It's very blatant and is causing discord in the whole department.
