Not always true. Our school gives as much as 50%+ off tuition to some that qualify. You can send you kid here for as low as $380 month if you qualify.
380 dollars/month for 3 or 4 kids(for many pro life families) who may make barely 50000 dollars a year gross(before crushing state, local taxes... though their out right federal taxes might be small). I see you have no grasp on what many lower middle class Christian families have to live on.
To be honest though the situation regarding education in this country is reflexive of this nations overall fall into immorality and can only be righted by a massive change of hearts in the country as a whole. Judgment has fallen and it is hitting the unrighteous as well as the unrighteous alike in this nation unfortunately.
A territorial balkanization of this nation may be the best the righteous in sections of this country can hope for...though the standards of living may fall for a time..
