I wonder if American students fleeing their country to save on education tax is more than anecdotical. BTW, the article mentions Germany, but isn't education cheap in most European countries?
If I was born in the US I'd never move to Europe to study anything tech related, being in a major university like Stanford or MiT just gives you so many connections and makes you able to experiment beyond your regular coursework. Just like someone said on a post here a while ago, the difference between you and your friend who studied at Duke is that Tim Cook is just a phone call away because they walked to class together every morning.
