““When we talk about building wealth, we ought to refer to one’s entire net worth, meaning the sum of savings and total assets, minus all debt. If you have $50,000 in your TSP and in other savings accounts, but owe $50,000 on credit cards, a car or two, and student loans, have you really built up any “wealth”? While you have saved up a tidy sum in the TSP and in savings accounts, since you owe so much to creditors, your total net worth in this scenario is actually zero.* Consider also that, instead of receiving interest and dividend payments in the TSP, each of your debts is charging you interest—and in many cases considerable interest.””
