Seems Tech companies are in collusion to not hire employees away from each other as well as setting compensation package amounts between each other.

A Wall Street Journal Article, U.S. Steps Up Probe Of Hiring In Tech describes the scene.

The Justice Department is stepping up its investigation into hiring practices at some of America's biggest companies, including Google Inc., Intel Corp., International Business Machines Corp., Apple Inc. and IAC/InterActiveCorp., people familiar with the matter said.

The inquiry is focused on whether companies, particularly in the technology sector, have agreed not to recruit each others' employees in ways that violate antitrust law. Specifically, the probe is looking into whether the companies' hiring practices are costing skilled computer engineers and other workers opportunities to change jobs for higher pay or better benefits.

You should read the salaries quoted, good god are they off the mark, except for higher management!

Of course H-1B and labor arbitrage, age discrimination isn't up for discussion. It appears the focus is on those upper management and executive class jobs. The ones actually designing and writing the code of course are considered disposable.
