From CityJournal:

Most federal programs offer states taxpayer money to operate programs created in Washington. EFS would subsidize private donations to locally designed programs. By encouraging states to sponsor nonprofit scholarship-granting organizations, EFS would encourage what R Street’s Andy Smarick calls “real decentralization.” In states where legislators may be on the fence about school choice, EFS offers an incentive to experiment, without imposing federal mandates. One state may want to provide scholarships to low-income students in failing schools; another, to support religious education; and another, to assist a nonprofit that gives scholarships to apprenticeship programs. EFS could accommodate these different efforts.
