the violent agitation by gurjars in rajasthan shows how selfish these people already getting the benefits of reservation r. they r already getting reservation as obc, now they want to b declared st, so that they can get more advantage at the cost of meena, who r in st category. meena r also said to b going to do violent protest against this demand as they not want gurjar to b declared as st. it is all so mean mindedness. i also understand that gurjars were rulers during 9th century.
seeing this state of affairs, i think that the only way out is to provide reservation only on economic criteria, with a provision of stringent penalty or fine, if anyone gives forged or wrong documents for showing his economic backwardness.
