I agree...people learn from experience as well as education, so obviously uneducated people CAN teach educated people.

Use commas in this kind of situation:
Therefore uneducated people, too, possess valuable knowledge which they have acquired through experience.
Whenever there is "too" in the middle of a sentence, and it is used to mean "also" you should use commas.
First, it is not fair to undermine the level of intelligence or wisdom of an uneducated person. Due to various socio economic reasons such as poverty, political instability, cast constraints, etc., some smart people are deprived of receiving a good education.
Wow, very impresive! You write strong sentences.
In the Tao Te Ching is says "much knowledge means little wisdom."
Chapter 48 says, in pursuit of knowledge, every day something is acquired. In pursuit of Tao, every day something is dropped.
Look at Richard Rodriguez's "The Achievement of Desire" if you want to see a great essay about this.
You did very well.
