@TGM:
I would imagine that malnutrition could play into mental growth, especially at very early ages.
As for you spending money to benefit your children, that is fine, but there should also be a publicly provided education system for others. That system should be paid for by everyone, as it is now. What some of those in the free market camp seem to wish is for there to be an overclass and an underclass. If we did not have public education, and private schools cost as much as they do now, there would be no way many people would ever get an education. Overall, that would be a great detriment to our society, though, it would lead to your children being well off, and in charge of things, until there was an uprising. Yeah, you can provide for your kids, and maybe that is what you want, for them to be some of the few that can actually read. Why not educate everyone, and let everyone attempt to innovate, rather than just the well-off kids?
When we look at policies, some of us look at how they affect our immediate family and children. Social Security should not exist, because *I* could do better with the money myself. Public education should not exist, because *I* could afford a private school. How about if we look at it from another direction? If Social Security did not exist, what would the people that depend on it now do, and would you be happy with that outcome? I guess for you, and many others, the answer is yes. I do not think that I would be happy with forcing millions of people that are unable to work into the streets. If public education didn't exist, I would have been fine. My family had enough money, but many of my friends wouldn't be. They are holding down very good jobs, but couldn't have done it without public education and scholarships, even while working full time. Losing some of them would be a detriment to our society.
