Doubtful. Most people (including Mcgee) probably don't want the world to know they didn't pay back a debt for nearly 3 decades
When you say it like that I can't help but factor in inflation. Even though McGee paid the loan back, the value of it will be significantly lower today than when he borrowed it.
However the value of Carmack is significantly higher; there's something to be said there (though not sure what exactly it would be).
