I worked for a corp at a similar "golden cage" position, where switching would incur a pay-cut and working harder for longer hours. Eventually I changed company. I looked at the beurocrats around me and realised I'll end up like them - my tech skills on the decline, learning only how to manipulate and cover my ass.

We grow in the face of adversity and challenge. I think as an ex-Googler you'll have a choice of interesting positions that will benefit your career in the long run.
