As CAR pointed out – you do have options. You are not forced to send your kid to a public school, unless your kid has special needs (not necessarily due to medical condition, but also due to socio-economic conditions).
You don’t have options when it comes to paying your taxes. You have to pay your taxes and some of that money will be used to fund the public education system regardless of your participation in that system.
I am not saying that public schools are outperforming private schools. Au contraire, I am not satisfied with my kids’ school and I am reevaluating options.
