I wish it was that simple. Around 1913 auto workers were paid about $2.50 a day, so compare that to todays dollar. What can you purchase now for a days pay?
I remember my grandfather talking about working for a Dollar a day. Of course that was many years later and I didn't comprehend what I was being told.
Typical cash has no value, it's just a convenient way of exchanging what you have for something you want. Even gold has no real value. You can't eat it or drink it, so it has a value of whatever someone else will exchange for it. Usually cash.
Inflation exists and it always will. It's part of the carrot that hangs out in front of you.
That $75,000 house from the 70's is now worth $200,000. If your investment was Ok, you can now take that inflated $200,000 and buy another inflated $200,000 house just like it. If that $75,000 cash had beeneere "saved in a drawer somewhere, you could now buy a $75,000 house.
