Which of these economic situations would you prefer to find yourself in?
A- Your salary is stagnant but prices fall. Where this happens, your real purchasing power has increased. It's called constructive deflation. And even if your salary falls, but prices fall faster, you are still ahead.
B- Having your savings taxed 2%+ a year by inflation.
Drop your thoughts
A is impossible to have in practice. There is no such thing as constructive deflation. Human population is increasing so the money supply increasing as well and increasing the money supply drives the prices higher because the manufacturing can't keep up with the other two. As a result, somebody somewhere has to starve.
We are having the second option because we don't have other choice.
We you look at it we are exactly like viruses, consuming our host till there is nothing left of it.
