Major screenwriting gripe

Something that upsets me in the world of screenwriting is the pitchfest that charges writers to pitch a script. The screenwriters' union, the WGA, does not approve of agents who charge a reading fee. Now tell me -- what is the difference between an agent charging a reading fee and a producer charging a pitch fee? Both say, I'll look at your story idea if you pay me. It either case, it's asking a writer to PAY for the opportunity to show you something that might make you a lot of money. The wGA really disappoints me by not condemning these pitchfest affairs the same way they do agents who charge reading fees. It's the same kind of conduct. Shame on the WGA. End of sermon.
