Yes.

They should be exempt if need be. However, in schools where there are substantial numbers of children who would qualify as exempt, there are alternative programs so that a few parents are not paying for the majority of the kids. There's just too much free $$ out there that's not being utilized to force kids who can't pay to pay. If public school is free. . .so that all children can receive a good education. . .then it needs to be free.
