I sent my kids to a Baptist school nearly 30 years ago, at a time when I couldn't afford tuition. The Pastor and I worked out a deal and I became a bus driver in my time off from my regular job as part of the tuition. Where there's a will there's a way. Hang in there, it's well worth it.
Most parents do have the means to either pay for good private/religious schools for their children or homeschool. The problem is that many parents aren’t willing to sacrifice or do extra work like you did. Too many parents think that they are paying taxes for public schools, so that should be good enough.
When parents decide that a couple of lattes a day from Starbucks and a new car every three years is more important than their children’s education, there’s a disaster looming.
