Oh man, feels like I haven't been here in ages 
Ok, got something I need help to wrap my head around.
I'm a freelance filmmaker, making short videos for companies. I have a set $ rate for my services and every time a company contacts me to make a video, I give them an estimate how much each video will cost to make, and we go from there.
Now, when I hire an actor, I would assume that they are a self sustained business. They provide my company with a service and brings their own name, brand, fan base etc. However, the actors don't have "charging rate" but wait for a filmmaker to dictate how much actor's service will cost.
I understand that typically we normally write in certain $ amount for the actor into the budget, but I just don't understand why don't actors set their own rates? I'd think it would be much easier for an actor to plan their business if they set their own rates.
Providing an actor with my rate is the same analogy to me as if I went to a hair dresser and told them "I only have 10 dollars to get a haircut, can you cut my hair?"
So... why don't actors set their own rate and treat themselves as businesses?
