Why is human's main problem a lack of critical thinking?

While we talk about corruption or pollution, I feel the root cause is our lack of critical thinking.

Here is a quick breakdown of why this is happening:

Rote learning over questioning in schools.

Blindly following authority and cultural conditioning.

Fake news and propaganda spreading without any fact-checking.

Emotional reactions taking over logical reasoning.

If we don't fix how we think, we can never fix how our society runs.

What are your thoughts on this?
