Does one level just by how much XP they have or also how much GP they have (or some combination)?
I ask as I saw in another thread that it appears characters are indeed strictly limited to character wealth by level. As such a character who saves money by crafting items themselves won't actually save anything as the full price of the item he/she crafted would count against WPL.
In which case feats for making any extra money would be either useless or they'll help you level faster.
Do I have that right?
