Liberals (typically Democrats) and Conservatives (typically Republicans) have very different viewpoints about education. Liberals see the public school educational establishment (the unions, the government bureaucracies, the University Education Departments, etc.) as the way to educate children (except occasionally for their own children).
Conservatives believe results are the important thing, “Is the child getting a good education?” Government ads claim that every day 7000 children drop out of school and millions more graduate lacking basic knowledge. The educational establishment isn’t meeting society’s need to prepare children for adulthood.
