I have never heard of a professor "forgoing their own salary" to keep the lights on. I'd be surprised if this was allowed, actually.
Also, for what it's worth, I did a PhD and a post-doc and have a nice biotech job that pays well. It's not an easy road (what is?) but it's not as bleak as all-that, if you enjoy doing science.
