It's not a matter of valuing a good education, it's a matter of making a limited education investment go further. I doubt the harms of whatever ideological tampering are so severe as to outweigh the sheer educational benefits to low income Americans and probably many middle income folks from developing nations.

It's not like individuals are free from their biases either. Humans can always learn more and change their beliefs, but without the basics of education they'll never get to a point where they can critically analyze the world around them.
