I'm talking about the money Facebook made off the IPO shares, not the net worth of Facebook employees.

Changing the IPO price wouldn't have changed that. If they'd opened at $15 and popped up to $35, Zuckerberg's net worth would still be the same as it was when it opened at $38 and dropped to $35... but Facebook itself would've gotten much less money out of the IPO.
