Why r u comparing rajni with Shah ruckh khan. In front of Rajni SRK is a bacha. Rajni is there in the industry right from 1970.. SRK has come 1989-90. it is not a good comparison. But some things u can compare.
1) Rajni organisations are there from 1980, means his age at that time is 30 years . I donot see any even with SRK he is well past 40 2) Till now Rajnikanth has donaed some 200 crores to poor people in tamil nadu in the form of charitable trusts. I donot know SRK has a mind like that. 3) one more Remuneration. To the world Sivaji has collected 200 crores in just fifty days. I donot SRK can never dreamt of his movie doing that much of business .
One more to the world he got 20 crores as remuneration. Unofficialy his remuneration is more that 50 crores. Not even in the next life SRK can think of this amount.
