The idea that there is ever a bad time to do a startup is ridiculous. There are horrible times to attempt an exit. During the crash would be one of them.
People have been trying to raise money for distressed debt funds since mid-2007. One of these times they could get the timing right, although investor cash might be drying up for them.
I think the point he almost makes about there not being many jobs anyway is a good one. when there are lots of well paying jobs, there is social pressure to take one.
When things are quiet, there is less of that pressure to go get a nice job, and you can take your time (kind of forced to).
I think someone else mentioned it here as "someone else moved your cheese" - I like that.
