From the new Friedman Foundation for Educational Choice 2014 Schooling in America Survey (Page 45):

“A school voucher system allows parents the option of sending their child to the school of their choice, whether that school is public or private, including both religious and non-religious schools. If this policy were adopted, tax dollars currently allocated to a school district would be allocated to parents in the form of a ‘school voucher’ to pay partial or full tuition for their child’s school.”

According to Friedman’s new survey:

In 2012: 56% of American Adults supported vouchers.

In 2013: 60% of American Adults supported vouchers.

In 2014: 63% of American Adults supported vouchers.

Here are comments direct from renowned economist Milton Freidman about how school choice such as a voucher system benefits lower-income families.
