I've watched reservation benefits go to the same handful of already well-off families within a community generation after generation, while the poorest members of that same community never see any real change -- that's not fixing the original inequality, that's just handing the same door to people who already found other ways through it.
The Supreme Court's 1992 Indra Sawhney judgment already introduced the 'creamy layer' exclusion specifically to address this concern for OBC reservations, meaning the mechanism to exclude wealthier members already exists in law -- the live debate today is really about whether that exclusion should extend to SC/ST reservations too, which currently remain exempt from it.
