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.
