You choose to microwave a burrito, a dog chooses to poop on your carpet, and an android chooses to start with its left foot instead of its right. All of which depend on chemical reactions that were put in motion by the same processes that spin the Earth. There's more to learn when you accept the deterministic reality. I also think it's a much more ethically sound philosophy as you're capable of forgiving more often.
In regards to the discussion at hand about college, it's a sociological mismatch. We value higher education and yet the market can't supply for that value. We have a huge service sector that replaced manufacturing. On the upside the jobs are a bit safer, but there's not as much wealth produced per capita from service labor and so the market is flooded with part-time and underemployed workers. Worse still for those with degrees is the fact seasoned professionals aren't retiring.
There's no single cause. You can even throw in a spiel about jobs not training workers anymore and high schools pretty much lowering standards to get graduation rates up. It used to be dropping out of high school didn't mean the end of the world. Minimum wage was set at around $10-$11/hour (inflation-adjusted) and you enjoyed cheaper benefits.
