Stupid post, but you know how in Raiders of the Lost Ark, you see his house and it's a typical, even slightly small house. Not exactly living the high life.
You'd gotta think he'd be pretty ticked off when he finds out all the other archeologists pretty much just get a permit, and have a relaxing cup of tea in between some digging where they uncover artifacts, meanwhile he's making the same amount of money, but nearly dying about a dozen times each excursion.
I'd be like "I should be living in a mansion right now....not one of these other archeologists have to be so good with a whip that they can whip the gun out of a guys hand right before he shoots you, or in good enough shape to run away from a giant 2 ton boulder....this is some bullcrap".
He kept giving all of his good loot to museums. It's hard to make much money when you just give your work away for free.
The Great Circle game makes a point that a lot of what he finds goes to the university museum where he teaches. He does get results but the world changing finds always slip through his fingers and a lot of the events that happen along the way can't be substantiated.
