One of the selling points to legalize MJ in NV was the tax receipts would go directly to our underfunded schools and underpaid teachers, then they reduced school funding from the general fund similar to the increase in MJ taxes. The net result is the schools are still underfunded, this is why tax increases are always viewed with skepticism, even though (nearly) everyone agrees we should better fund our schools we’ve been burned before. Same is true of gas taxes, everyone wants better roads and bridges so we raise the gas taxes and then watch the money get spent elsewhere.
Most people dont have the means to home school, one side has been fighting for school vouchers for years (so people could do exactly what you propose) but they’ve been fought at every turn by the other side because they want all the kids (or at least their money) in public schools.
It’s disingenuous to force people to spend thousands in taxes to support public schools and then tell them to spend thousands more on a private school if they disagree with what the public schools teach.
