I never claimed that they had other great jobs offered. Telemarketing is a ****ty job, but it is far from the only ****ty job around, they do have other ****ty jobs to choose from. Other jobs that doesn't intrude on people's private spheres and annoy them in order to sell products. They chose the one that does, so that warrants a response that makes them aware of that. I have as much respect for the people that choose telemarketing as the "last option" as for the people that send out spammails. Or perhaps I should be grateful that these people didn't choose crime instead? Is it some sort of blackmail scheme, be nice to your telemarketer or he will break into your house and rob you or sell crack to your children? They made a poor choice and they need to know it.
Regarding commercials and marketing there is usually an unwritten contract between the sender and reciever, tv commercials for example, or ads in newspapers or in stores. The customer gets something in return for the commercials, or they are in an environment (in the street or in stores) where making them aware of a product can be an advantage and where the customer has accepted the presence of ads. Telemarketers on the other hand intrude on your private sphere and on your time, blocking the phone line in order to sell you a product. Noone on the recieving end ever asked for them to call, and they push products that most people had no use for prior to the call.
Sorry to get all riled up, but I just get so fed up with seeing that lame excuse about them "having no other choice" served again and again. They do. And even on the off-chance that they haven't, well they just have to face facts that there are jobs out there that are going to make you unpopular, and being hypocritical about it and cuddling them and making their work easier so they have more time to call up and bother other people is not going to help one bit. Quite the contrary.
