We can’t simply print ever more money to infinity, can we?

Yes, we can actually. We should also tax away excessive wealth that is unearned, which a modest amount of inflation does.

The concept of "debt" is largely misunderstood as it applies to a sovereign fiat currency. Without a restraint from a pinned currency it simply becomes a reasonably accurate indicator of the "net' money supply, not a mortgage on productivity that should, or even can, be paid down.

Would you be concerned that the general public's "savings" account was too large and recommend reducing it as a means to improve the economy? That could only happen if the ROI was extreme and flooded the economy with interest payments on new money created, which would represent logic opposite to that which is applied currently.
