The debt to which Mr. Stark refers is the debt that creates our money supply. One debit of debt = one credit in the form of a dollar entered into circulation (simplified).
This debt increases essentially exactly in equal proportion to how much money we have in circulation, hence Mr. Stark’s claim the Nation becomes more wealthy with an increase in debt.
The interviewer fails to make this distinction and misses a great opportunity to get Mr. Stark on camera explaining how our present system is Constitutional and best for the Republic.
When did an increase in the money supply equate to an increase in wealth? I assume by wealth we are referring to GDP. Increased federal borrowing in the long run, is not an efficient way to grow GDP. The private sector does a much better job with borrowed funds.
