James Potter's profession?

The question still remains how James and Lily Potter amassed all that 
gold at Gringotts.

Definitely they both didn't go into government service, although one 
of the couple could have. James could have struck it big as a 
Quidditch player after Hogwarts. No confirm or deny so far, but you 
think ROn would have mentioned it first off.

We do know there was a joke business of "Padfoot, Prongs, Moony and 
Wormtail". Given the success of the Weasley Twins already, this seems 
the most likely so far.

But if that business was actually successful, why are today Sirius 
Black, Remus Lupin and Peter Pettigrew all so poor, and the Potters 
the only one who made money?

Was Potter indispensable to the business' success and without him it 
failed after his murder? Did Potter graduate to creating more 
important magical artifacts leaving the partnership? Did product 
liability suits come up wiping the remaining owners out?
