the Evil Line

A survey of school voucher programs in DC finds not much difference:

Students who participated in the first year of the District of Columbia’s federally financed school voucher program did not show significantly higher math or reading achievement, but their parents were satisfied anyway.

But wait, there is a difference:

The $7,500 scholarship that families spent was about half the average public expenditure per student in the District of Columbia public schools.

This last line is misleading; replace "families" with "taxpayers". The bottom line is that school choice provides more bang for the buck.
