Paying a fee to audition for a casting assistant in order to 'demystify the casting process' is like paying a hooker to become a better conversationalist.
Actors should not be paying a casting associate's rent - for meetings and readings - when they can barely pay their own.
It costs a lot of money to be a starving actor.
Take up revolution in the service of art.
Lift up your fellow actor and you will be lifted too.
