I broadly agree with MikeNV here. However I would urge caution to anybody who is thinking of investing in gold - only do this if you are going to take physical possession of the gold: at the moment, for every ounce of actual gold being traded on the market, there is at least another ten ounces that only exist on paper.
Something else to consider is that - in America - people that owned gold were once (in 1929 I think) forced, by law, to sell it and Americans were banned from buying it. This type of manipulation of the gold market - done at the behest of the banks - could well happen again.
I wouldn't, either, advise a return to the gold standard. Over three quarters of the world's gold supply is either owned or controlled by the banks: including all the gold in national depositories. A return to the gold standard would, therefore, still leave national economies under the direct control of the banks.
What we really need is for the establishment of state owned national banks that have the power to print and issue money. This would still be a fiat currency but it would not - as is the case now - have interest levied upon it at source.
