Very random thoughts on Gringott's Bank

Since Harry's inheritance just came up, I've long wondered how this bank 
works.

First tho I wondered how the Potters amassed so much gold.  What did 
they do for a living?

On to the bank.  This gold is simply in a vault, hence it's not getting 
any interest.  Shouldn't it have been invested?  With all the money 
handling going on there, surely the Goblins conduct business in much the 
same was as the RW, investing and such.

Is Arthur Weasley's pay automatically deposited in their vault?
