My hunch was right, the breadth of knowledge of the Letsrun posters seems to know no bounds, and I thank each of you for your thoughtful posts.

"all fiat currencies eventually go to 0."
Yes, this is the ultimate fear for any currency holder, and the pictures of wheelbarrels full of German Marks can make anyone cringe. Alan Greenspan advocated back in the 1960's in a book entitled "Captitalism: The Unknown Ideal" for a return to the gold standard for just such a reason. However, the other side of the argument is illustrated by Ben Franklin when he first moved from Massachusets to Philidelphia in the 1720's. He found the economy absolutely stifled for a complete lack of currency and advocated for printing it, of course he was a printer. But in general, this raises another question I have been unable to solve, and beg your insight.
If you go to a gold standard, than the money supply could not increase any more than the increase of the supply of gold. For the simplicity of argument, let's incorrectly assume that there is no more gold to be mined, and we have a set and finite money supply. If the population increases at just 3% a year, with the supply of currency fixed, than the demand for that currency must increase, all else equal, which leads to deflation. Just to illustrate, if you house is worth 1000 ounces of gold, and gold gets more and more desirable, than in a few years you'd be happy to get less than a 1000 ounces of gold for it, since gold is more dear.
The problem with deflation is that it creates a larger real effective interest rate: what you pay in interest less the inflation, or in this case, the deflation rate. So if some budding capitalist needs funds to start his business, he will pay some interest rate, and it may be low, say 3%, but if deflation runs 3% (in line with the population increase), his real rate is 6%. So ideally, to eliminate any inflation or deflation bias, you need the supply of capital to increase at least with the population growth, all else equal. I would think, as man becomes more efficient, economic growth could increase at many multiples of the population growth, so the money supply would have to increase at a much larger rate, just to eliminate the inflation or deflation bias.
So, even with you fiat currency fears, what choice do we have? Fix the amount of currency, or back the currency to a fixed standard like gold, and suffer the effects of deflation and reduced economic growth, or take your chances with the government printing presses?

"P = DIV/r ....
when the fed cuts interest rates r goes down which means stock and bond prices should go up"
This is an excellent illustration, thank you. However, my dilemma is with r. The fed only controls short term interest rates, not medium nor long term; only the markets control the latter. If by decreasing short term interest rates the market smells inflation, than, if rational they would demand higher long term interest rates. Than, if you discount those future cash flows with the now higher long term interest rate, than that P goes down. I've checked, and those 30 year rates just don't seem to want to go up. So I guess the market either doesn't fear inflation, thinks it will be short-lived if it does spark up, or perhaps, as I conjectured, is irrational.

" While the drop in the dollar is theoretically advantageous for our trade deficit the November data just published shows that the deficit is still widening at 9%. This is a huge long run problem for the economy and will be as big a drag on the overall economic well being of the country as inflation could be."
Again, another insightful post that just makes me ask more questions: do trade deficits matter? I am not sure that they do. Any country selling to us more than they are buying from us is pretty much taking an IOU in the terms of US dollars. The question is what do they do with them. It seems from all the news I've been seeing is they are investing those dollars here in America. They are taking huge stakes in our companies. So essentially, ownership of the corporations, real estate, and other American assets are being converted into foreign names. While most will have a guttural reaction to that, economically, does it matter? At least provided they keep the assets here in America and run them as well as they have run previously, I don't know if there's any major negative economic impact.
Thanks again, I am humbled by your scholarly replies.
