No, there is always the Promissory Note where you promised to repay the amount. The original can sell that note to anyone. The promise still exists.
Accounting 101.
The idea that someone’s wages were garnished “because they didn’t say not to do it” is pretty funny.
Promises and wages and garnishing and accounting and notes.
No mention of law, though, like the federal requirement of debt validation when challenged. Or why that's even necessary, or why someone who bought a "note" might not be able to validate a debt they "bought." Or the many legal differences between wage garnishment and debt collection.
What's funny is that you have such arrogant opinions without understanding the difference between these issues. Maybe you shouldn't have stopped your education at Accounting 101 - if you'd taken some more classes, you wouldn't be so overly impressed with that one.
