If you have a college degree your unemployment rate is 4.7%, with a big chunk of that 4.7% in the building related fields (architects, civil engineers, etc... are having a tough go right now).

It's a double digit unemployment rate if you just have a high school diploma. Meanwhile manufacturing output has actually increased dramatically, without adding any significant jobs. That's what I find scary. The U.S. is the worlds leading manufacturer (I'm having trouble finding data from 2009, but in 2008 we we're the largest manufacturer by a wide margin). Yet, manufacturing jobs are way down. I'm not sure those jobs are ever coming back. We've gotten crazy good at automation. Until the cost of human labor in the U.S. decreases by a rather large percentage, we'll continue to build ever more sophisticated systems for building things.
I'm not sure what that leaves us with.
