>and are generally incentivized to get you as much money as they can since they generally get a percentage of your yearly salary as their pay

This is not quite true. They're optimizing for throughput, not max dollar value. If they optimized for the maximum amount of money they could get you that would come at the cost of their time which would lower their throughput of placing candidates and hence the maximum amount of money that they can personally earn in aggregate.

They'll still try to spin you that line though.
