[pointillistic]

I have pointed this out in a comment on this thread but would like to repeat it in support of your list.

Myth #1: People hire younger workers over older workers because of the money. This is not true. Think politics and psychology first. People who move up the management ranks often have political or social skill superior to technical skill. They slimly don't what engineers who are more technically savvy or not subservient enough around. Not so the young greenhorns or even immigrants. Competent, seasoned engineers can't be as easily manipulated.

There is no substitute to experience, no matter the spin.

And often the obsessive coders pay little attention to the office politics. This leaves them exposed to the career obsessed suits. Politics and human dynamics first, money distant second, as always.

While I suspect you're correct in your first point, why can't both be true (control and money)?

As for your last point, http://www.jerrypournelle.com/archives2/archives2mail/mail40...; it's self evidently true.
