G. F. Brandenburg, retired math teacher in the D.C. public schools and major-league blogger, asks the most important question about the funding of public education in America: what if every child had the same quality education as the children of Donald Trump, Hillary Clinton, and President Obama?

That would mean small classes; experienced teachers; a broad and rich curriculum; a wide choice of courses in the arts; beautiful facilities; an excellent offering of sports and physical education; and more.

Surely you will say, “We can’t afford that!” Yet we had problem spending trillions on wars in the Middle East that cost many lives and did not end terrorism, probably increased it.

The greatest barrier to funding excellent schools is political will.
