Do you really believe the graph and what you just said?
During the 70's and the oil crisis the Fed did a very poor job handling inflation.
4% inflation is very high. Losing 40% of your saving every 10 years compounded to financial elite on top of taxes mean no ordinary citizen will be able to have any saving.
Only if your income doesn't keep up. If you sell goods or services those prices rise w inflation
No, this a common misunderstanding. Even when you pay raise comes timely, is is only neutral for your consumption, not for your savings in money and money denomitated securities. It makes saving in money impossible, and force savers to investments involving risk.
Savings in money do not carry risk - when the money is good. I mentioned also money denominated securities, because they loose value to inflation just like money. It is basically loans - you lend money for others to invest, but still take a share of the risk.
Old advice for prudence is to save some money - which is risk free when the money is good, when you are comfortable with saving in money you can invest. With bad money, this is inpossible. Please distinguish saving in money from investment, it is not possible to discuss these things in a constructive way if the wrong words are used.
So inflation in both consumables and wages is neutral to consumption, but kills savings in money.
You should understand that anything you do with your money will carry some level of risk. If you spend all of your money then you could lose money in the way of late charges and interest payments if you had an emergency and needed to spend more money then you had. If you invest in the stock market then you risk that the price of your stocks declines more then the amount of dividends paid. If you invest in bonds then you risk that the issuing company is not able to repay their debt.
