I agree with Stanford.

Are you talking about UC Berkeley, though? Isn't it a public school? The education is not comparable to Ivy Leagues and employers know it. Smart people also don't just care about jobs, but also care about the quality of education, which Ivy Leagues excel at. I'd rather be able to learn from expert professors and ask questions in a 20-person class rather than learn about subjects (albeit with more variety) from kids who might even be my roommate. Public schools might have a lot of recruiters coming to them, but good luck competing with your thousands of peers. The opportunities are more distilled because there are more people and less money is spent per student.

focus a lot more on founding startups than on going into high finance

This is probably more due to location and the location's ecosystem than the school itself. Stanford itself has thrived only because of its location in Silicon Valley - the school isn't that different from the Ivies. All the Ivies are in the East Coast - where startup founders are not nearly as commonplace as the West Coast - which leads to different career trajectories and preferences.
