2) A new grad at a startup gets, what, $100k in salary and some equity? If we're talking a three year stint at a startup, you're effectively asking a worker to invest ~$500k in exchange for that hypothetical equity. In the broadest strokes (obviously everything depends on the deal), what kind of equity does an angel get for half a million dollars, and how does it compare to the amount of equity the new grad gets? And it bears pointing out that that new grad equity is subject to all kinds of games and deception. Of course, the usual response is "you just have to be smart enough not to be scammed!" Perhaps, but I know tons of people (including myself) who are apparently just too dumb not to be scammed but are still smart enough to be gainfully employed at a safe job.
I don't think that had a large effect on my compensation, if any: I joined at L3, which is what most new grads are hired at, and my salary before Google was low enough that I don't think it pushed up my offer at all. I also didn't get offers from multiple places, which is the sort of thing that (a) results in higher offers and (b) is the sort of thing new grads usually do.
But ideally someone hired right out of school would be up for sharing their comp?
edit: Oh, I see you were in Boston -- that's a great deal then. I still wouldn't want to work for Google for idealogical reasons, but I can see why the money would attract others. You also had ~9 YEARS of full time experience at that point, which makes it a lot less impressive.
Taxes would be higher but we donate 50% of our income (https://www.jefftk.com/donations) so I'm not sure how you'd count that?
Also, I didn't have ~9 years of full time work when I started at Google, I had 3.5. My first full time programming job started fall 2008, and this was Spring 2012.
Also, donations are discretionary, so you wouldn't count them at all -- you would just count your salary minus your tax rate (not counting deductions, so that the average Joe can get some context).
