Is there life out there in the land of agents

This is nuts, who reads these, anyone, is there anyone out there, my email is mable1002000@aol.com I've sent out about 500 emails and letters to these so called agents who want so much, demand more and give nothing, such a waste of time, technology is going to waste of these self styled low life's, first they lead you on, they bring you in for the kill and then ask for money, one must wonder how many really god authors have gone unknown due to this bunch, please, someone, any one, tell me there is at least one good agent and one that is taking need authors. Why do these guys place ads if they don't want submissions???????
