Agreed (but would you say Dave Ramsey’s financial education is bad? He hates all debt with a passion! I think in his case it’s having been bitten hard by over-leveraging early in life).

Either way, I use a different classification (other than “good debt” vs. “bad debt”) when making the decision to accelerate payoff or invest — the inflation-adjusted interest rate.

If you got a student loan at 8.4% when inflation is 2%, it’s worth accelerating its payoff, despite this being a “good debt.”
