A peer of mine posted this and I found it valuable:

I was struggling this week to easily explain why a tax bomb isn’t as scary as it looks.

After all, 100 grand in twenty years isn’t the same thing as 100 grand today.

I got rescued when I recalled a scene in the movie Die Hard.

When they point the camera in the direction of Nakatomi Plaza, it shows the cost of gas in LA as only 74 cents a gallon. 

That was back in 1988, and now the price of gas in LA is about three bucks a gallon.

Hence, when you see that you’ll owe a huge sum in a couple decades (if you’re not PSLF eligible), then divide it by 3 and you’ll get a rough guess as to what that would feel like in today’s dollars.
