Many of the pavilions at the 2010 Expo in Shanghai are phenomenal, both inside and out. The USA pavilion, however, is neither. But far worse than being visually unimpressive (which it is), the essence of our representation at the largest World's Fair carries an even sadder message. I've been inside some pretty mind-blowing pavilions this week, which makes the failings of the USA's--the world's largest economy--even more shameful. http://www.popsci.com/technology/article/2010-05/usa-pavilion-disgrace
