We have a large number of developers with 20+ years experience. You aren't seeing their resumes because they're here and don't have a reason to leave.
I've been here 12 years now, and if you can't match the 25 days vacation, 10 sick, 12 holidays, plus bump my salary 10% or more, I won't even call you back.
Edit - I'll also note that I'm a project manager by title. I don't have personnel responsibility, so I still get to spend a lot of time on technical issues (and even some coding).
