@JSAMcFarlane @MPgh @KeithDJohnson @oldredsubby Definitely hitting an old philosophical war injury here! I actually believe that there should be NO private schools, K-12. Not any. To home school one would have to produce at least a bachelor's degree and it can't be in religious studies or some such hokum.
Even now, there should be no tax deductions for private schooling. College tuition should be a deduction only for state or community colleges/universities, not for Yale or Dartmouth.
