Google does not owe you a job. If every company had an agreement to not to hire with any other company and there was nobody who didn't work for any of these other companies, then they would have to terminate their agreement or go out of business. But of course, that wouldn't happen because that situation would incentive companies to break their agreements or not form them at all (such as Facebook). Sure, Google and Apple drive wages down in the same way that Facebook drives wages up.

But to answer your question directly: Yes, if nobody wants to hire you... nobody wants to hire you. I don't see why Google should be forced to hire you anymore than you should be forced to work at Google.
