Proximon, I was stationed at Scott AFB, in the same area (St. Louis Metro) that the sign in your avatar was changed. Sadly it happened after I had left the area. If only I could have seen it in person. I'll have to try and dig up the article, the story made it in the Belleville News Democrat.
It actually made it nationally... I saw it on the evening news originally I think.
whats the ideal economic system?
There isn't one. Because Man is flawed, all economic systems are likewise flawed.
Usualy a sistem with a AMD 780g or 785g or 790gx chipset+a intel cpu and no dedicated video card will be pretty efficent or economical by the raw-power/consumption but this scenario will never happen.
