Why is it a poor comparison?
Here's what I'm hearing on this thread: On pref night, a student might have two options. Either one would be OK, but ultimately, she has to choose which one to rank first. Lots of pros and cons might enter into this decision, but relative cost cannot be one of them.
Similarly, a student might have two college acceptances. Either college would serve her needs adequately, but ultimately, she needs to decide which one is her first choice. Lots of pros and cons might enter into this decision, and relative cost should be part of the calculation.
Why? How come pragmatic considerations don't belong in one decision process, but they do in the other?
