Are, it's impossible to have that at all points. The point is to strive for it, not achieve perfection.
If we don't strive, then with people like DeVos in charge of federal funding, public schools will be gutted and the problem worsens.
"That means the Federal contribution to elementary and secondary education is about 8 percent" - https://www2.ed.gov/about/overview/fed/role.html
It really makes me wonder what we need the Department of Education for...
According to DeVos, we need it to undermine public schooling by directing tax money to private schools.
