Yes, it has lost value over that time, but in a relatively stable and predictable way
People's savings are getting robbed in a stable, and predictable way. The problem is that to "opt-out" of this robbing, you need to play it investor. You can't just buy a gold coin, and sleep easy that it'll worth the same in 20 years, as people could a century ago. (Again for a variety of reasons, not need to be discussed in here.)
and very slowly
Supply of fiat currencies expands by around 14% per year, for the last 60 years, on a
weighted average. That's not slow. It means that in 5 years, they've robbed half of your savings.
In the right context, and in diversified portfolio of many other instruments, USD has been a perfectly viable investment.
USD is a viable "investment" if you compare it with other more volatile investments. But, if you look at it from the perspective of someone simply wanting to preserve their wealth for the future, it's like a bucket full of holes.
So you want a world where you just make money without even trying?
No? I never said that? I want a world where I can work, make money, and be able to hold the value of that money into the future, with the lowest risk possible.
Again, stop thinking about finance the same way the Illuminati conspiracy buffs did when they invented that stuff in the 1960s. The world has drastically changed and all of your assumptions about economics are obsolete.
Correct me about my economic assumptions, then.
