Gotcha. I'm glad that I've forced you to ignore my argument rather than addressing the elephant in the room.
The average student loan debt in 1980 was zero because the vast majority of people could get by on free and public high school education btw. Especially if we assume that we're talking about the median income household.
To achieve this equivalent to 1980s lifestyle, we're talking what? $200k extra debt burdens on every average / median person? $40k in student debt and $150k++ in extra housing debt? Plus 4 years lost in education (as 1980s folk could work those 4 years instead). How is this a better or even equivalent life?
