> What evidence is there that vouchers are helpful?

> James also said that school choice has “not proven effective at improving education.” That is also highly misleading. Ten of the 16 random assignment evaluations on the topic find that private school choice programs increased math or reading test scores overall or for student subgroups at a fraction of the cost. Only two of the 16 random assignment studies, both of which examined the highly regulated Louisiana voucher program, found negative effects on test scores. And four of the six rigorous studies on the topic found that private school choice increased educational attainment overall or for student subgroups. None of the six studies found that school choice reduced educational attainment.

> Who benefits? (the answer here isn't "everybody")

Of course not everybody. Public school teachers and administrators will suffer tremendously should school choice be more widely adopted.
