Meanwhile in most of Europe, college is free. I wonder how their attendance rates have fared in comparison.
Take this anecdata with a grain of salt; it's nearly 20 years old.
The European governments didn't distort the market to make universities as grand and expensive as the American ones (where the price raised 1500% since the 80s).
European universities are sad places which get the job done for relatively little money. You're still spending 3-5+ years of your life though, and that's a currency you can't earn more of.
