> the net present value of a college education isn't something that shows up in the calculation.
Sometimes it never shows up. Mine never did. And I still have student loan debt.
When you're calculating values, consider that different students have very different levels of student debt despite receiving the same education. Rich kids with the bank of mommy and daddy don't need to borrow at all.

It really depends on what "substantial" and "easily" mean.
If you're truly living paycheck to paycheck, then you are actually in danger, because paychecks can easily stop, e.g., layoffs, and then you won't be able to "easily" afford your car payment.
This is not even mentioning other unexpected expenses that can arise and suddenly make your easy car payments not so easy.

No, because your net worth is not negative.
