If you think reservation will do any good, think again. In India only 20 % of graduates are employable. That means only 20% graduate get job what they want. Open category is still 50 % open. This verdict will create further biased in Private sector. Their are very few Govt. Jobs So OBCs will have degree but no job. On other side all Open category student will be easily absorbed in work force.
Also ,Their is no dearth of private engg, and medical college. Plus I heard foriegn company are coming in education sector. They will directly train your so called merit guys and export them (this is what happening in AIIMS). You guys won't loose anything technically, Only looser will be OBCs.
