"...fosters deflation..." the first pernicious fallacy, right off the bat - the idiotic notion that deflation is bad. It is very bad under a debt-money regime, by design. Nothing fosters deflation (while forcing inflation) like a collapsed debt-based monetary system, once the economy is incapable of further growth, further credit expansion. That's when the piper comes calling, and the end game is the disappearance of all currency from circulation. All such currency was created with the intent to destroy it, even while siphoning interest that was never created. That's when all debts are still due and owing, but the supply of future Ponzi scam marks, who are need to provide payment for past debts, have dried up. No more Peters of the Future left to invite into the debt-creation musical chairs circle to pay all the Pauls of the Past. And when that happens, paying existing debts plus interest, the deflation is catastrophic.
Under a sound money regime, with no collectivized "business cycle" based on fractional reserve lending, deflation and inflation are isolated, localized, natural phenomena - as good, natural and necessary as inhaling and exhaling.
