ELI5:What is the incentive for real-estate agent fight for the lowest price for a buyer?

I understand that the buyer's agent gets a part of the seller's agent's commission, most of the time.    

A lower price, no matter who pays the commission means lower income. I do not trust the notion that "honor" would make them seek the *best, lowest price*. Reputation is unlikely to be a concern. A buyer will rarely find out, they could have gotten a house for much lower. I am a jaded five years old.      
     
*What is the incentive for the buyer's agent to seek a lowest (not lower) price?* 
   
Thank you.

Look at it this way... saving a client $10,000 cuts into the agent's take home pay about $150 (6% commission is $600, half to each agent who then pay half to their brokerage). Saving a client an additional $10k is MUCH more likely to result in referrals to friends/family and repeat clients, earning them well more than the $150 they gave up on the transaction.
