The gap is closing for the first few years of engineering vs finance (first 3 years of comp in finance is definitely a lot lower now vs 2007, whereas first 3 years of comp at GOOG post 2009 has exploded), but the gap grows as you approach your mid 30's. When you're getting to $300k at GOOG, your buddy is over $500k at GS as a VP (VP is middle managemnt in high finance and iirc the high fliers get there in 6 years). Fast forward a few more years, and you're making $500k at GOOG and the buddy is well over $1MM. The gap will continue to grow in size exponentially thereafter.

I guess $300k vs $500k is much improved compared to $1X0k vs $500k that we would have been looking at a decade ago though :P

In addition, perhaps the parity is better when you compare median results rather than upper quintiles.

Btw, first year management consultants make nowhere close to $100k (though they can make up for it with Starwood points and frequent flier miles on United -- no joke). You'll only top $100k once you're an associate, which is after your 2+2 (2 years as an analyst, 2 years of bschool). Only 3-5% of the analyst class goes straight to associate. Students who enter as an analyst are doing it primarily for the great education and training McK/BCG/Bain give you, and definitely aren't making the choice based on monetary incentives.
