Paying off med school debt with credit cards? Taking out federal loans to finance investments?
What could ever go wrong..
1. Credit card debt is dischargeable through bankruptcy, student loans are not.
2. Since she has a family, taking out fed student loans is wise. It's a form of insurance. In the event of death, fed student loans are 100% discharged. Her spouse/kids inherit that money. Plus, they pay no taxes on it, including the investment gains, because it's below the threshold for inheritance taxes.
Her mode of thinking is more akin to the average MBA, which is far beyond the scope of the average med student/doc who can't figure out a dollar from a hole in the ground.
