I don't rely on PvE to earn gold via picking each cent dropped by them. There are lots of ways to earn them.
Here are a few examples:
- I farm locks and sell them via consignment shop. Bam! easy 14k/pc
- How did I get them? I bought lepre. How did I acquired lepre? I saved enough story tokens to buy a colton and sold it for about 200k
- I also sold items which are already of no use to me but still has good marketable value (lowbie pinks) etc.

seriously, if you rely on picking up gold for money and do not have the patience to farm and buy & sell then its not the game's problem anymore.
