Earlier quoted context omitted.
The reason these questions are not front and center is that the people with money don’t want to talk about them. And, the ensure we are kept busy with cheap gadgets, entertaining tv and movies and enough controversies that don’t matter to last a lifetime. Alsr, the population is less educated and able to actually think critically about these issues than they used to be.
Citation on that last point? The amount of people I know who were the first in their family to attend college, and sometimes even graduate high school, makes me question that people are measurably less educated.
On top of that social media has put people in echo chambers and force fed them outrage content. People who are outraged and surrounded by peers who are also outraged are less likely to think critically.
I personally think that the replacement of newspapers that invite critical thinking by yellow journalism and social media has had a more significant effect on critical thinking than the drop in education quality.
