When asked about the prohibitive cost of the program, he responded:
Finn: Considering the quality of the program, it's going to be a real bargain for parents. But we are also seeking alliances with schools and after-school programs and philanthropists that can help bring this program within reach of thousands of low-income families. (And of course for those who enroll via a "virtual" charter school, there's no charge at all.)
While this doesn't completely assuage my my concerns, it does make me feel a bit better.
