I seriously question the accuracy of the list when Neil Peart is 26th...?!

I have a very hard time believing guys like Chad Smith, Travis Barker, Jon Fishman and Tre Cool have THAT much more $$ than Peart. And, Dave Grohl is $103 million richer...?? I mean, if you asked 100 drummers who their greatest influence has been 98 of them will cite Peart. Now, I realize "most influential" doesn't equate to "richest" but in Peart's case, it kinda does since he's been at the top of people's list for over 3 decades and given the fact that RUSH is a billion-dollar-plus enterprise.
Neil the 26th richest on a list of 30 richest drummers....... PUHLEEEEEEZE!!!!
