It's important to remember that average student loan debt is still "only" about 30-35K. This is rising, but 100K or even 50K is by no means the norm.
Valid point, however, we're in a Gifted forum where little that involves our children is "average" with many if not most of them being in STEM fields (which we've discussed as often taking longer to complete) going to high cost private colleges, and / or going onto graduate degrees, all of which boost the probable debt amount of the average student of this forum.
