Those who got earlier were also deserving only. MS Subalakshmi, Bilmillah Khan, APJ A Kalam, Moraraji Desai, Kamraj, Lata Mangeshkar, Vinoba Bhave. These Padma awards, or any award like Nobel, don’t carry any brand value until bestowed on and accepted by such great deserving people. Award gets that status only because great deserving names got associated with it. In a way it’s exalted status of such recipients which makes awards like noble and Padma look important and coveted. When Ravindra Nath or Curie received Noble, it enhanced award’s status not other-way. Otherwise there are awards given everyday, everywhere by someone to someone. Not all are Padma or noble.
Another corollary of this statement could be also deduced that even though these awards are big enviable brands but perhaps are still not worthy to be bestowed on some who are of much bigger social status than these awards like someone suggested giving Noble to Gandhi. Likewise greats like Ambedkar, Subhash , Patel being themselves much beyond these small recognitions, didn’t need posthumously Padma awards. It is politics.
