Low interest rates have skewed investment sentiments from Hellenic and  Roman times until a couple of hours ago.    With -0- rate of return in  any sort of bond; the Fed (with a BBB- real world rating),  States (47 states  are technically bankrupt) junk bonds or even decent corporates, you are  behind the ever increasing inflation rate now along the lines of 9-10%.
This  forces the average person as well as institutional investors to seek  returns that actually show on the plus side of the income statement.   PSI's require AAA ratings, available in only 4 Euro states and -0- US  states.  UST's are AA plus according to the rating sock puppet S&P
Where does one go to find some decent returns?
The DOW--yielding -0- for the last decade? NASDAQ--down 50% since the peak of the tech bubble?  S&P? I don't think so
Gold and silver have returned 10% annually this last decade, keeping pace with or exceeding inflation rates.
I'm  no different that anyone else. I'd like to stay ahead of the return vs  inflation game.  Seems like gold and silver are a good choice.
And I can spend it if I want to.
Stagflation  is what we have now, just like the 1970-80 time period.  10% inflation,  10% unemployment and a rapidly increasing national debt.
The  solution then was severe.  15% rate on T bonds vs today's 3%.  Prime  rate 19%.  Silver and gold went up between 1000% and 2000%.
When  the UST is forced to increase rates to 6-8% as a minimum to sell its  junk bonds to an increasingly skeptical buying public,  the value of  these bonds will drop by 50-75%, crushing the portfolios of those  foolish enough to invest in this form of  paper.  
Every time the  government debases its currency and is forced to increase rates of  return to draw more foolish money into the sovereign coffers, the  citizens wealth and enterprises are absolutely destroyed, along withe  country.  Ever time. 
But this time it's different, it's it?
Yes, it is different this time.
This time the whole world financial system will be destroyed.
