Why are so many people worried about hyper-inflation? It seems obvious that deflation, like what happened during the Great Depression, is the biggest concern right now. Furthermore, inflation hurts creditors (banks). With inflation, it's easier to pay loans back, and if inflation is higher than interest rates, then banks take a loss. With deflation, the money they lent out, and the money they have, is worth even more in the future. So, to sum it up, inflation hurts creditors and helps debtors, and deflation helps creditors and hurts debtors. If one is to assume that the banks have absolute control over money, you'd have to assume they'd want deflation.
Yes, but if a person would start to save money heavily, perhaps even invest a portion in stocks or bonds and real estate, deflation would actually greatly benefit this persion as well as the banks. And the best part, saving is not even that hard, just eliminate all previous debts, don't get any more new loans, and deduct 20% or more from your monthly wage/allowance (in the beginning, use a savings account / CD).
