One of the biggest issues that I see is that schools no longer teach children how to think.
I agree, and am sad to hear that this phenomenon is not unique to the USA. Critical thinking skills must be taught, and they need to be taught at an age appropriate level starting as early as is possible.
And in countries like the USA (which is where I live) where the courts are favoring the ludicrous idea that "parental rights" means that little Johnny or Janey can never be exposed to any thought, practice, or worldview that does not comport with the parents' own, you get to where we've gotten in terms of public discourse, too.
I am so thankful that my parents did not believe that I should not be exposed to things they did not agree with. They expected that I would be, and that there would be discussions regarding "what we think" versus "what you've just heard about" and that, sometimes, the latter would be what I (or one of my siblings) would believe, even if that was not permanent.
Little unthinking individuals were not tolerated in our household.
Even the Catholic junior high and high schools I went to had discussions regarding "what we think, and why," versus "what the world thinks, and why." That's the foundation of creating a person who's well-rounded and eventually thinks for themselves by examining as much information, often conflicting, and coming to a reasoned decision about what to believe.
