We know from studies and reports that online charter schools provide inferior education.

We know that they have lower graduation rates and lower test scores than brick-and-mortar schools.

We know that they have high attrition rates, as students enroll and leave within a year or two.

We know that children enrolled in virtual charter schools do not have the opportunity to interact on a regular basis with other children of their age or have face-to-face interaction with live teachers. We know that they will not develop the social skills that come from such interchange.

We know why they are a growing business: They make millions for their sponsors.

So why do parents continue to enroll their children in institutions with such a bad track record?

Here is the answer: The demand for virtual schools is a sure indicator of the dumbing down of the American public and the triumph of American capitalism at its greediest.
