Most may not have the funds to employ others as babysitters for 13 years, but there we have a separate discussion.
It is not cheap.
I spend approximately $500.00 on school supplies per year per child, But- hubby makes enough that I can stay home and survive on one income.
I also have two computers and many other resources that other families may not be able to afford.
I agree with you wholeheartedly that it is ultimately the parents responsibility to supply a good education to their children ,and that this should be done at the most minimal involvement of the government and the taxpayer. But since I consider an educated citizenry to be a benefit to all taxpayers- I see it as our responsibility to offer some educational resources to families who can not afford to homeschool or to are not able to homeschool.
Even though I pay taxes for a public school system- And I myself do not benefit from that system at all, I consider it my duty as an American to pay taxes so that some child somewhere will get an education.
I agree 100% that the taxes are too high and the by product of public education, in many cases is mediocre...My ideas to change that are obviously different than yours.
