'I’m not making my agent any money'.

If you’re auditioning then you’re earning them money.

The agents most important business relationship is with the casting directors. By submitting good actors to the casting director that lets the casting director have a good session. 

A good session means their submissions to the producers are high quality.

That means the casting director will get hired for other shows. That’s how they make their money.

They are thankful for the agents who send good actors. The agents are thankful for the actors who do good auditions.

Neither group ever tells the actors this - but that’s how the system works.

The actors earn the agents money not just by booking jobs, but by keeping the system working.
