I'm a first year student at Penn. One offhand thought:
CC often begins with the assumption that an Ivy education is going to cost 4-5x as much as another education, perhaps at a state school. This is simply not my experience at Penn.
Let's run the numbers. An out-of-state MUP at Portland State will cost around $17,000/year, inclusive of fees. The same figure at Penn is $40,000. The difference between these two over the course of a two year program is $46,000.
At Penn, some of this difference will come in the form of loans, but not all. There are need-based grants, and Penn is very generous with merit-based grants as well. (My merit aid alone is $12k, and many of my classmates have similar awards.) Subtract that $12k and we're down to a $34,000 difference. Subtract the grants from the total need-based aid, and we're at a difference of below $30,000, sometimes much lower, for the two year period. If CC's math held, that $30,000 figure would be about twice as high.
There's no question that Penn is more expensive. But a "$100,000 planning degree," as CC is fond of discussing, is way off the mark. (Not to mention the benefits of living in a place with a low COL, like Philadelphia.) In addition, the single greatest expense of full-time grad school is the lost income from not being a full-time employee. Compared to that, a $15k/year difference is relatively minor.
Whether a place like Penn is worth the extra 15k/year is the subject for a different post (I believe it is, but there are arguments on both sides.) But the actual difference is less than you might think.
