One statistic I haven't been paying a great deal of attention to until recently (and even now I haven't paid as much attention to it as I should be): the price of an intercultural studies degree.

It can make sense to pursue a degree at those levels if you're going to graduate and enter into a decent paying job (e.g. non-profit administration, pastoral roles, etc).
But if you're thinking of going into missions - and raising support - those levels are obviously a big issue. Especially if you don't have scholarships or the financial wherewithal to pay them outright, and you are going into debt.
This is just an opening post on the subject; I'm sure others have written about this to a greater degree. Links to articles or analysis in comments would be welcome.
