What an incredibly blinkered point of view. One of the worst possible eventualities from the writers’ POV is – or should be – exactly what you theorize: That the public drifts off and finds other things to do and discovers that, “Hey, I don’t need to watch so much TV anyway.” Or “Hey, it ends up all these reality shows are just as entertaining [or un-] as scripted TV.” Fewer viewers = less advertising revenue = fewer shows = fewer jobs. The chief pressure point for the writers is that the public is going to get aggravated at the lack of new entertainment and effectively pressure management to start cranking it out again, which of course would require settling with the writers. And the writers should be concerned that thus far, the majority of the public doesn’t give a damn about the strike. Just as with baseball, the worst possible outcome for both sides is that the public stops buying their product. I frankly find it amazing that you think that the end-consumer is irrelevant to the outcome of this or any strike occuring in any consumer-based field.
If your consumers can get by just fine without your product, who becomes irrelevant: Them, or you and the product you’re selling?
