For the perspective on the hugeness of the amount involved, look at the following calculation from which it is evident that the money is sufficient enough to feed 1000 people for their lifetime.
A 420,000,000 total amount
B 420,000,000 / 20 = 21,000,000 total meals that could be bought @ 20 rs. per day
C 21,000,000 / 1000 = 21,000 total days assuming 1000 people
D 60 * 395 = 21, 900 number of days in a persons life span
This amount can build 10 kilometers of 4 laned highway and similarly numerous other things. I remember my college days when our dean advised us to be agents of change. I appreciate that statement more now than at any other time in the past. If we are in a position and have the ability to effect change for the good, we should give it a shot. Mr. Minister with 42 crores was one such agent and it is a lost opportunity now.
I do appreciate that this is a sensitive subject. I personally donate/offer during my visits to places of worship and it gives me immense satisfaction as well. We should always distinguish between being responsible or being excessive. We can of course endlessly debate on the exact line that differentiates responsibility and excessiveness. Are we not matured enough to get into such a debate? We can clearly see it.
