Nope. That is still because of his talent.
He is the RK legacy. Monetarily RK or the Kapoors haven't been dominating since their last ATBB Ram Teri Ganga Maili. It's been downhill ever since.
The family influence will always be there. Me explaining further why that influence exists makes it sound all dirty.
In short to say, Ranbir didn't had it easy because of the Kapoor clan not being dominant is self explanatory. Yet, he is preferred / supported, one main reason for it is something I wouldn't dig much. Second main reason is talent which he has proved over & over again.
