It's simple, whenever a couple billion dollars is printed up for a mortgage crisis or economy stimulous, the money you have becomes worth less... I don't know how to make that more clear.
it's perfectly clear. what isn't clear is why you think it's bad. i thought we agreed that gradual, stable inflation is good for the economy? did i miss it somewhere where you provided evidence that current monetary policy is producing rapid inflation? or dramatic changes in inflation rate?
So here's my example, Gas averaged 1.73 in 2003. It now averages well over $3.00 - In that time, as crude relates to something like, oh, lets say gold - the price remained relatively unchanged; proving that the rise in energy has nothing to do with a shortage and everything with your dollar being worth less.
your example is one commodity and two random points in time. why not use use 1.38/gallon in 1981 and 1.34/gallon in 2002? or we could settle on just using the actual annual rate of inflation. the chart below illustrates how much more stable, and closer to optimal targets inflation rates have been during the fiat currency era. bravo, fed.

Because some commodities become more plentiful. When the commodity that your currency is tied to becomes more plentiful, your currency becomes worth less, or inflates.
sometimes your commodity becomes gradually more plentiful. sometimes it becomes rapidly more plentiful. sometimes it becomes relatively more scarce. with corresponding effects on your currency. not stable.
The difference is, if they are not corrupt, I still have my commodity that is worth something. In a fiat currency, all I have is a piece of paper that I have to trust the world will continue to honor. When that trust is lost, all I have is a piece of paper. Take a dollar to the U.S. treasury and ask they exchange it for something with value and they'll try to sell you something.
in the case of the fiat currency, you trust that the currency issuer will manage monetary supply to produce inflation in line with stated goals and in accordance with historical precedent. in the case of a commodity backed currency you trust that the currency issuer won't act to change the ratio of exchange. in both cases you are have no guarantee other than trust in the currency issuer. what exactly is the difference?
when i take my crisp, clean 2012 dollar to the treasury to see what they'll exchange it for, you should bring a wrinkled, old 1962 silver certificate dollar and see if they offer you anything more valuable than they offer me.
It SHOULD have worth because it prevents printing in excess making what you have in your pocket worth less.
i understand the visceral appeal of this line of thinking. but just look to the historical data. it is a false sense of security, the data show that governments will debase commodity backed currencies whenever they need to do so. while being prevented from using the tools of a fiat currency to promote economic growth.
Are you honestly telling me that you have ALL of your finances wrapped in investments that have intrinsic worth?...
i have plenty of guns, i don't need yours. my money, aside from what i need for the next month or so, is in productive assets and real wealth. none of which will have much of any value if society and rule of law collapses. in such event, i doubt if a pile of gold and gun will provide much more security. you're unlikely to have the only gun.
Disagree. Tightening lines of credit being loaned out to risky investments is not nearly the same as banks closing their doors. That's the difference between gradual deflation and dropping off a cliff.
can we agree that our economy would collapse without capital markets and the ability for entities to borrow money? if we agree on that, let me ask you a question for our period of gradual deflation. let's call it 2% annual deflation. Can I borrow $1000? i'll pay you back $990 in a year, that's a full 1% over our deflation rate.
Economic growth has occurred due to the advent of new technologies making production easier and faster.
how many of those new technologies would have been developed as rapidly if companies didn't have access to capital? how many if consumers weren't stimulated to spend, providing more expansive markets?
In the last 10 years alone...
it's interesting that you always wish to limit the discussion to data from the last decade. the gold standard was eliminated in 1973.
