With a game as complex as Pathfinder efforts on the part of players in the group to make the best possible character can have negative effect on the campaign as a whole.
It can sometimes be the case that one member of the party, although the same level, is markedly more effective in than others.
One traditional approach to address party imbalance is to stigmatize players, call them munchkins and take away their toys.
Some GMs spend inordinate amounts of time closing loopholes in the rules, removing problematic magic items, or nerfing class abilities as they.
I'm getting too old for that.
As a matter of respect the players should be working together to ensure that the party members are on a mostly even footing. Rules savvy players should help their comrades to bring the party up to a common playing field. If a power imbalance arises the players will be asked to fix it.
Conciets:
Players acquire wealth from treasure or employment. Attempts to game the system or storyline to get more wealth than other party members is problematic
(trying to sell statues, assessing window dressing, repairing broken items to sell as antiques, exploiting supply/demand economics etc etc.
