Public education is the longest and purest form of communism ever experienced inside the US, and it proves its complete and utter failure. A top-down, centrally-planned, government-controlled system where the labor force gets lazier and less effective every year, and the students get dumber and less capable every year.
In my 12 years of public school, I had 2, maybe 3 teachers, out of dozens, that I would feel comfortable allowing to teach my children. Disbanding the US Dept of Education would be a net benefit for the future of the US.
