An online preschool closes a gap but exposes another

It is not a program for children of the rich. It is geared to lower-income families who have fewer prekindergarten options.

EXCERPTS 
FOWLER, Calif. — David Cardenas, a mechanic and the mayor of Fowler, knows families in his town want high-quality and free daylong preschool.
But options are thin. A government-subsidized program fills up fast and fits only a small fraction of the town’s 4-year-olds, he said. A private program that closed a decade ago was unaffordable for many of the 6,500 residents of Fowler, a predominantly Latino community of agricultural workers in California’s Central Valley. Otherwise, there are a handful of private day cares.
