Look at the curve of the historical data:

This cannot be sustainable. I think the original assumption of 4% inflation might be too low. It went up 2.5x between 2000-2011. So, if you take that same trajectory, then Ivy tuition would be around $157k/year. So, 4 year would cost ~$628k instead of $400k. Maybe it will flatten out from here. Who knows…
