Glory
See fame. The glory of an IRS Auditor comes with the ability to look through the financial reporting equivalent of the Matrix and hone in on a detail that brings to light wrong-doings of multi-national corporations who tend to make people's lives stink anyway.
There's also glory on a micro-scale when you're able to find instances when individuals have overpaid on their taxes, and you're actually able to issue a tax refund. Tax refunds are paid by the government when the amount owed by an individual or business is less than the amount paid. Even though the money has already been paid, people see tax refunds as "free money from Uncle Sam" and therefore bask in the warm glow of their windfall.
