This is what we often hear from the privileged few that are allowed to create money, then loan it out and charge interest on those loans.  Of course if adding more money to the total money supply were such a good idea then allowing each of us to have our very own printing press to print out as much money as we need and just skip the loan part would be an even better idea.  I'm sure we'd have the world's economy firing on all cylinders in no time.
