Good luck with your belief that paper is equal to gold.
You do know that with any amount of money in the bank, assuming you are making 7% intrust an nothing drastic changes, with that money a year from now you will be able to buy 3% less product/food than you can today.
There is a reason that most wealthy people have lots of "stuff" an very little cash in banks. Cash is fine as a barter tool but holds no value. Things on the other hand hold value, especially things that don't degrade.
Well I didn't say that I believe paper and gold is equal. But what do you think most people buy gold with ?
Your assuming that inflation will be 10% over the next year. So if you invest the same money in to something that paying 13% return then you would be able to buy 3% more product/food than you can today.
Rich people have lots of stuff because they have paper to buy the stuff. When I only have a bag of carrots and the rich guy only has a bag of gold who will be full at dinner time.
