I agree with you LesPhelps and I've had similar experiences:
First, I'd have to say that a big reason the Crash Course is not a household topic is that most people don't want to consider it, even if they essentially agree with it.
My wife is an excellent example. She is totally in agreement that we are in trouble, but doesn't want the topic discussed and doesn't want to do anything more than very basic preparation.
Others who I've shared the message with treat me like a lunatic. That's not going to change until people are ready. Peak Prosperity is not alone in this. The message has been around literally for decades. In some cases, as with Peak Prosperity, it has been presented intelligently and in a manner hard to refute. Yet, it still is largely ignored.
I believe a major event will have to take place to make people pay attention, possibly even larger than another stock market crash.
I've had the same experience. I've started identifying more and more people who have inside themselves a deep vague sense of forboding for our future. But it's too overwhelming or frightening for them to deal with, so they push it down deeper into their minds/hearts, and try to get back to every day life. They don't want to think or talk about it, but they sense something VERY BAD is just around the next bend in the road. They try not to think about it, but it keeps popping into their consciousness.
Maybe they don't need more facts or evidence, but maybe they need someone to help them emotionally deal with what they fear. Many need more of an emotion-based intervention, not a fact-based intervention. Most of us here have responded to the fact-based intervention (The Crash Course, for instance). The personality types of the majority of people need an emotion-based intervention. Their style is not to deal with the facts until they have the emotional resources in place to do so. Secondly, most people's initial attention is NOT captured by facts, but by emotions. Many of us here deal with the facts first, then get our emotions involved. (All of that does NOT mean that emotion-based approaches are devoid of facts, or that fact-based approaches disregard emotions. It DOES mean people start at different places to deal with the same problem.)
Whatever happens next, I think we might benefit by appealing to the hearts as well as to the minds of our neighbors. (BTW, within The Crash Course the section about exponential growth using Fenway Park filling up with water as an illustration is an appeal to emotion, and a powerful one.)
What's the old proverb? "When the student is ready, the teacher will appear."
