Part of the issue is that the 10% unemployment rate is not equally distributed across all demographics.

If we generalize the desired startup labor pool as college-educated adults over the age of 25, the national unemployment rate drops to 5.1% (http://www.bls.gov/news.release/empsit.t04.htm). I can't find a great source, but I'd also wager that when you factor location (NY metro) and industry (technology), the unemployment rate drops even further--almost to the point of natural unemployment.

If you fit this profile you shouldn't have a difficult time finding work, and hence we have a "war for talent" in the face of high, national unemployment.
