The socialist know they cannot instill their "dream" (communist) government until they disarm the masses. The communist/socialist (now the Democrats) began their infiltration into our education system in the 1920s and 30s. I don't know what they think of their success, but IMHO (in my humble opinion)they have gained far too much. The information is on the WWW. Run a good search engine and check for "public schools socialism" or "education communism."
This Link is one I found that seems to give a fair account of how it is/was happening.
