What has been lost is widespread confidence and faith in those institutions that previously served as the pillars of society -- the church, the king and the nobility. Now people are completely on their own for their worldview. What's become abundantly clear is that people are very, very bad at constructing useful or reliable models of the world. Left to their own devices the people will readily embrace all sorts of nonsense, the more extreme the better. Some will turn to drugs and some will turn to ranting about crisis actors and some will turn to video games.
None of this is a cause for concern. These people's lives are still orders of magnitude better than those enjoyed by people just a century ago. A life wasted playing video games for 12 hours a day still beats one wasted slaving away for 12 hours a day on the farm.
What is disconcerting is that the "poison" is seeping into the vital and core institutions and systems that contribute to our extraordinary quality of life. The author is concerned about the suicide rate (which impressively continues to break new records every year) but what should really be frightening is the extraordinary poor governance that Americans have enjoyed for the past 20 years. (Seriously, trillions of dollars flushed down the drain on completely pointless wars.) When the real engine of American prosperity sputters out we will have much more significant and difficult problems than a bunch of dumb, bored kids getting high on dope.
