There is no unsolvable conflict between vouchers and public schools. BOTH can flourish if implemented intelligently.
Here’s the absurdity of the current scenario. I send my three kids to catholic schools from k-8 and it costs me about $3,100 each per year. So by the time they are done, I will have spent about $83,700. The local public school district spends a total of somewhere around $9,000 on elementary ed kids apart from special ed (Overall gross is about $14k per kid, so I’m giving quite a bit of leeway for the special ed budget). Had I sent my three kids to public schools, they would incur another $243,000 in taxpayer costs that they now spend ZERO on since I chose catholic schools. In return I get a measly couple hundred dollars a year in state tax credits, but I’m charged around $7,000 PER YEAR on my real estate taxes to support the public schools (yes that’s JUST the schools portion).
This is insane and unjust. BOTH me AND the public schools would benefit from a LIMITED voucher program that reimbursed private school parents for $1,000 per student per year as long as that student scored at grade level on the same standardized tests the public schools use or met the remedial path goals set for the year by a district special ed specialist. Now if the public district was like mine and currently has about 5% of kids in private schools and the private school enrollment increased to fill all vacant seats it might rise to 7%. If there are 10,000 total kids in the district limit that means that the district currently spends 9,700 * $9,000 = $87million in annual operating costs. Under my partial voucher plan, the district enrollment would drop to 9,300 and (long term) annual costs would drop to 9,300 * $9,000 + (700*$1,000) = $84.4 million. Alternately, the district has an extra $2.6 million that they can use to restore stuff previously lost to budget cuts: art programs, music, vocational, etc.
Instead, they stubbornly insist on the current policy of increasing costs and de facto double taxation of private school parents, which results in steadily decreasing private school enrollment, increasing public school enrollment and subsequent tax increases to pay for the increased public school enrollment. Madness.
