Again, the point is that there is more to job compensation than money (at least for me). If it doesn't pay enough, and the perks aren't worth it, then don't apply. Or apply, and then say "no thanks". Nobody is forcing a job on you, and there are quite a few people who would enjoy working for PA at some unknown % of market value. And don't conflate non-monetary compensation with doing good in the world, they can be two different things. Hell, in the case I made before they are two different things.
Speaking of non-profits, you know they run Child's Play[1], right? Raised $17M+ over 10 years. I wonder who's doing all the tech support, web dev, etc for that? Smart money is on whoever holds the advertised position.

You may not be in it for the money, but any for-profit venture certainly is. Imo, if you're going to work for below market pay, you should do it for a non-profit that really is trying to make the world better with limited resources, not a company that is capable of paying what you're worth, but would rather make a slightly higher margin off your hard work.
