Fair points. I don't have historical data, but my observation is that the issue of brahmins controlling/dominating lot of sectors was a real problem at some point and the reservation system was a populist response that did provide some benefit for oppressed castes, but created a whole bunch of other problems and unintended consequences. And its still remains such a hot button populist issue no political party would dare implementing the required reforms. The unintended consequence is the emigration of a lot of people from the "higher" castes. I guess its hard to say if it had any material impact on India's progress but the "higher" caste population that doesn't have the means/resources to emigrate is put in a real difficult situation.
iyer or iyengar is their traditional surname probably. same way as a family name in the US. why discriminate against iyers because they want to have a surname of their choice? most folks would be proud of their surnames. Is there a community that feels horrible about their surname?
No, these are not the traditional surnames. What I am referring to is a practice of legally changing the last name (typically father's or grand father's name) to Iyer or Iyengar. To me its a clear on your face statement that the person belongs to that caste and wants to flaunt it.
