This is a very naive misunderstanding of how the labor market for executives actually works. Executive compensation is set by the Board. Who is the Board? They’re all CEOs of other companies, who have no interest in seeing executive pay tied to performance. This is all a you-scratch-my-back-I’ll-scratch-yours situation, from people all in the Good Old Boys network of Harvard and Stanford MBAs. Tying compensation to performance is in nobody’s interest in this network.

You’ll be happy to see that I included hyperlinks to their Wikipedia pages for deeper context.
The thing you should take away is that, contrary to the GP’s assertion, the Google board is in fact not composed of juts a bunch of CEOs from other companies.
It’s true, some of them are former CEOs of other companies. Some held other executive positions in Alphabet and non-Alphabet companies in the past or present.
They still have a vested interest in perpetuating high levels of executive pay.
