Cultural dysfunction and poor parenting burden public schools with too many nearly ineducable kids who consume disproportionate resources and, as the result of unfunded mandates, consume massive administrative and teacher time, and prevent the hiring of adequate professional teaching staff.

Thanks to excessive legalism, the hands of administrators and staff are tied when it comes to maintaining control of their classrooms, so that the least able or well-behaved consume too much of a teacher's time and energy.

The portion of school budgets devoted to overhead, administration, and pension and other benefit overhang is ENORMOUS, but normally concealed from exposure lest the flat-out lie that budgeting more for "education" will actually result in more time and resources being devoted to teaching be exposed.

I think it's safe to assume Johnston, though undoubtedly a bright and well meaning fellow, is a tool of the teachers' unions and other defenders of the status quo.
