I said in the post that I am from the United States (in North America).
The schools in the US used to place a strong emphasis on education. In the last decades we have adopted the "Pedagogy of the Oppressed" as the new models for schools.
Our schools block people like me (who wanted to teach mathematics) in favor of people who which to use the schools for political activation.
The twin result of this decision is that students in the United States are no longer receiving a world class education and schools are dropping in prestige.
IMHO, the way to turn this problem around would be for schools to focus on teaching subjects like math and science.
