Harry - I think that the only way some people are going to wake up is if they are hit with a clue by four. Disaster of some kind - everything that they are addicted to/making the center of their lives taken away. Fashion, gadgets, shopping, MSM/movie/etc crap all gone, etc. Then they will be face to face with their empty lives and empty hearts, and then their character will have to come to the fore.
I am sure that many are so determined to keep sleeping that nothing (in this life) will help them. “None so blind as he who doesn’t want to see”.
I do think disasters of one kind or another (or several in a row, or all at once, who knows) will wake some up. Not that I’m wishing for disaster. A healing crisis, maybe.
