Indeed, the nepotism inherent in the old-but-not-so-grand-anymore party is reminiscent of the accounts of rajas' and badshahs' attitude of entitlement and expectation of being waited upon by doting servants. This is just blind belief in the elusive concept of purity of lineage, and definitely not a measure of success.
It is worth noting that success is defined as overcoming adverse circumstances and working hard to better oneself in all spheres of life. One does not become successful by being born in a royal family or a particular dynasty, which is the clown prince's dubious claim to fame. The true definition of success can be applied to Modi, who has worked hard to overcome adversity and reach the top.
