You know what I find really ironic?
The successes of startups in Silicon Valley really drove up the compensation of programmers. But these same startups have founders/managers who openly state they prefer younger programmers, and direct their HR/recruiters to act accordingly. And now, we have whole classes of programmers who can't get a job at all.
It's pretty obvious no recruiter lost his/her job for passing on resumes of younger programmers.
Also, the SV is really the bastion of anti discrimination. Which is great. But they replaced it with something else, ageism.
Just my 2 cents.
