Ok, i got it wrong, they are interest free, its the inflation you pay, not the interest.
But if the inflation is negative it doesnt mean the loan shrinks for the majority of us, as we are part of the new loan scheme, we're not really being diddled though are we..
Its current interest rate is 0%, but do we expect inflation to be in the minuses forever? No. It will be positive again someday, and then we will be paying interest again.
Dont get me wrong, its a brilliant loan, but only if you're using it for something worthwhile, if you're going to waste it then you're getting in needless debt, and you will be paying interest on it, just because currently people are not doesnt mean it will stay that way forever.
