While I do think that schools have been corrupted and need to have political bias
eradicated and replaced by rational teaching of basic subject matter and rational
thinking, I also suspect that the problem in some cases could be a lack of ability
by students. In the first 3/4 of the 20th century, most public school students were
able to absorb enough basic knowledge to survive and be productive in the
employment marketplace. It appears that is no longer true.

All schools, pre-k through university, should be;
privately owned,
non-government regulated,
non-government funded, and
non-unionized.

Then maybe children would be taught to read, write, do arithmetic, and how to think.
