Virtual Charter Schools: Cui Bono?

What does "cui bono" mean?

From Merriam Webster -

Usually, the phrase is translated as "Who benefits?"

With virtual charter schools, it isn't the parents, not when you see the gaping hole in the state's budget.  And they're taxpayers.

It's not the students, not when you see the following report.

From that report from the Center for Economic Studies at the U.S. Census Bureau, dated May of 2023, by Paul Yoo (UC-Irvine), Thurston Domina (UNC-Chapel Hill), Leah Clark (Census Bureau), Hannah Hertenstein (UC-Irvine), and Andrew Penner (UC-Irvine) (emphasis added by me)-

Abstract

Virtual charter schools are increasingly popular, yet there is no research on the long-term outcomes of virtual charter students. We link statewide education records from Oregon with earnings information from IRS records housed at the U.S. Census Bureau to provide evidence on how virtual charter students fare as young adults. Virtual charter students have substantially worse high school graduation rates, college enrollment rates, bachelor's degree attainment, employment rates, and earnings than students in traditional public schools. Although there is growing demand for virtual charter schools, our results suggest that students who enroll in virtual charters may face negative long-term consequences.
