As a senior at Yale right now, and seeing what most of my fellow students are going into next year, the Ivy League is great at pumping out over paid worker bees. See here http://yaledailynews.com/blog/2012/02/13/finance-continues-t... for the numbers going into finance (~20%) and just anecdotally I would guess there are only slightly less going into consulting. Finally, there are a not insignificant number (maybe 10%) doing some sort of engineering.
I graduated from Harvard, and like chris_b said with Yale, a not insignificant number of people went into some sort of engineering. It's not the plurality career choice, but it's not like the field is some sort of pariah at Ivy League schools.
