Preschool is actually one of the programs Obama pushes that I support.
Kids learn early easier than later. This program probably isn't as much benefit to children like mine who are read to nightly essentially from birth, or my 2yr old that knows all the letters and counts into the 20s. They do well because we work with them all of the time....and I still want them in preschool if available.
There is a pretty big segment of society that doesn't take the time to read with their kids, to teach them fundamentals, or the basic principles of being a decent human being. You don't have to look to far to see those kids. Getting them in early I do agree helps them get going and they won't be as far behind when they do start school.
I think this is a good thing to spend tax payer money on. Making our kids more educated should have an influence on getting more of them to be productive and successful adult citizens.
