For the most part, I think studies have found private schools really aren't much different than public schools, in either costs or quality. Although admittedly I haven't looked into the topic in depth. A quick google turns this up:

However, we most certainly should not be the world's policeman as we are today. And we definitely shouldn't get involved in wars as silly as our current predicament. China is a good example of what to do in terms of globalization: focus on growing your economy at home while making use of economies overseas to fuel your own growth.
This is more difficult for developed nations like the US, but not, I think, impossible. China and other developing nations like it have a big advantage: their populations relative to their wealth is large. This allows for cheap labor for a generation or even two. Thus they make for good industrial powers, creating what cannot be created without the aid of unskilled labor. The US and other developed nations can not compete in these areas, and quite frankly, they would be better off investing in other methods of growing the economy. To put it bluntly, if you are a company doing unskilled labor in a developed country which could be done in a developing country,
you are doing it wrong. There are of course unskilled jobs which can not be done overseas for any variety of reasons, but even these can be done by robots in an increasing number of cases. In short, if you are an unskilled worker in a developing country, your life may become a little less miserable; if you are an unskilled worker in a developed country, expect to see your demand fall, and the compensation if you do find a job to fall as well.
So what should developed countries focus on? To be honest, I'm not entirely sure. The big question becomes: what can you produce which a developing nation can not, or can not do as easily or cheaply. Some say information economy, some say outproducing through mechanization. In any case, the unskilled worker is pretty much screwed as far as prospects for employment. Such is to be expected though; the trend of globalization is no more stoppable and no less important than the industrial revolution in terms of the way it will change society worldwide. Developed nations can no longer afford to sit on their metaphorical thrones, as if they are some sort of nobles looking down on the peasants scratching in the dirt. We are among the peasants now, and we must scratch out our own place, wherever that may be.
Now to bring an end to my post, since it's past 10 PM and my posts tends to get long, rambling, and strange at these hours...
