2.) It allows state governments to provide free education.
The Tenth Amendment states that the powers not delegated to the United States government by the Constitution, nor prohibited by it to the states, are reserved to the states respectively, or to the people.

Therefore, as the Constitution does not say anything about the education system, or how it should be, the states have full freedom to decide whether to provide free education or not.
