REAL interest rates are those which don't need to be propped up artificially by Central Banks, they can stand on their own 2 feet and find buyers on the free and open market.Historical norms plus some would be a good place to start. Certianly not 0.25% to 1% as is the case now, only the likes of FED can supply money at that rate, because they print it out of thin air. They give it nice names like "highly accomadative rate settings".
More Debt than money is when existing Debt requires even more Debt to simply service existing Debts' interest clip. Such is the Debt fuelled ponzi Fractional Reserve banking system based on fiat currency. eg: Each credit card requires and even bigger credit to pay off the previous and its interest.
