Think also about Paul Graham. Y Combinator is a case of him monetizing a reputation that he earned (and, yes, he actually earned it) by standing up for startups in the depths of winter. I, for one, plan on making a strong and vocal case for Real Technology (it shall rise again) after the Snapchat/Clinkle frivolity blows up and humiliates the current cool kids. Being able to explain why shit went to hell ca. 2017, as it will, is going to help us make a case for building something better in the next iteration.
That said, it was a bad time for entry-level salaries, and graduate school admissions were ridiculously competitive in 2003-05. If you had a $60k offer (that'd be $72k today) you were in the top third of CS graduates, and non-STEM graduates were lucky to see $40k. I'd guess that the more experienced engineers didn't see a massive salary drop (maybe 10-20% at worst) but it wasn't a good time for job hopping. Certainly that feeling that one could get a 20% raise, just by walking across the street, died out.
It was a good labor market for finance because there was a lot of cheap talent. First-year Goldman Sachs analysts were only in the $60-65k range. (Bonuses could be 50-100%, but they were also working 60-110 hours per week.) Undergrad quants (that's rare but the positions exist) were generally getting $80-90k offers.
People expected housing prices to come down, but they didn't decline by much because there was this other bubble that was building at the same time...
