See it from another angle: People who are willing to spend their money on godlike items can only be a help for you. If you get paired with a team, and there is one guy who has bought godlike gear, your party will be able to kill monsters faster, which eventually leads to more (personalized) loot for you.
Loot isn't everything for me personally. I ENJOY playing the game. What's the point of tagging along with an uber-powerful character who does all the killing for you? Sounds boring.
