Quote from sprstpd:
As a sound national policy, I think you must reward people for responsible financial behavior such as saving money.
Everyone loses with high inflation, especially retirees who are living off social security which is based on faulty government inflation calculations to begin with. The discrepancy between reality and the government's perception of reality will get even worse with high inflation. I have no doubts that the government will make up more ingenious methods to massage the numbers so they don't have to pay what they owe on social security. The retired are going to be slaughtered.
To respond to this I would have to put aside my feelings that g-ment shouldn't really be involved in the economy at all.
But assuming that g-ment should be involved, as a g-ment you should reward people for financial responsibility, but not for hoarding.
Your goal is not for people to save their money, but rather to invest their money in growth. In any case, it is essentially impossible for money to be saved and not invested. The bank will use saved money to invest for their own gain even if you choose not to invest on your own, thus creating inflation unless the reserve requirement is raised to 100%. This results in much slower growth as compared to a country with a lower reserve requirement.
A person is only more wealthy if they are able to accumulate a greater proportion of the available currency. If the money supply remains constant, then simple population growth encourages hoarding. It is then becoming of the g-ment to at least have inflation equal to the population growth.
Beyond that, the best way to encourage people to invest their money is to create inflation which causes them to lose buying power if they don't invest.
