Yes, this effect I rant into years ago, I forget when...I was killing time by crunching some stuff in a spreadsheet comparing what I thought was real inflation (a destroyer of wealth and purchaing power) with returns in various broad indexes for equities, bonds etc and then exploring the best options as to risk/reward within those categories...to cut to the chase I was horrorfied at what I found, I thought I had made a mistake, I tabled it for a while and came back, after a while I came to the conclusion that wealth creation along the old model is largely dead and since then it has been revealed as a complete fraud, a chimera out of some Neo-Keynesian tragedy. The best thing you can do with your earnings is preserve them, in whatever it is that has real tangible value. When fiat ceases to exist for anything but firestarter and TP, when digital transfers have gone dark...what do you have?
It is not to say I do not jump into the chimera now and then to exploit something I think I can take short term advantage of, but all that is good for is the quick conversion to fiat and then into tangible value. There is nothing without risk, there is nothing without volatility, there is nothing with a return sufficient enough to actually grow what has been put into it at a rate able to overcome the corrosive effects of wealth destruction.
