I believe the answer for that is by promising something "big" around the corner will get people who might otherwise give up waiting and take action to wait just a little longer and before that date comes you put out another possible date. The newly awake have to feel this is all absolutely real and the veterans of researching these subjects must be convinced to keep going. I dont think there is a solution date. I think the pain will have to be ramped up on the lower classes before mass reaction point or country security event happens.
