How is it the US Dollar is Fiddling itself to Destruction like the Roman silver denarius ?

I wonder if they ran out of silver. Is the world running out of things to base the economy on. Only the intellectuals who are manipulating things would know the real answer. Its for sure the American people are kept in the dark about what is really going on. Its just odd how much things have changed so quickly and so little is reported about it in the news. I keep wondering what to do with my 401k. Then I wonder if it really matters what I do with it if you know what I mean.
