I understood. It is true that I cannot prove my assertions beyond a shadow of a doubt, just as one cannot prove global warming and the rise of CO2 levels are not just coincidence.

It's true that economists tend to overstate their understanding. But, I have much less ambitious goals. It is theoretically possible that small causes are the real source of big effects, but it is very reasonable to look at big causes for big effects. Your statement about monetary policy places you in opposition to just about everything I've read by or heard from economists. It could be blind luck that increasing the supply of money increases GDP, and can cause inflation if and only if the increase in money exceeds the increase in goods and services. Me, I believe that something between the understanding of fiscal economists, and monetary economists is closest to the best model. I agree that a great deal of humility is needed by these folks, because things like the "rule of 7" are not valid, nor is the idea that monetary policy alone can handle inflation. But, there are enough data, including the timing of the changes in the economy after changes in Fed. policy that matches expectations repeatedly to come up with a reasonable phenomenology. Your view, on the other hand leads to predictions that counter data. Yes, there could be a wealth of unseen effects, etc. But, allowed that type of latitude, I could claim just about anything.

First, Keynesian theory predicted that deficit spending by the government was the only way to counter a deflationary depression. Look at the size of the deficits from '33 to '37. Look at the growth in the economy during that time. In '38 FDR was worried about the Federal deficit, and balanced the budget. The economy failed that year. It is true that other countries, Japan and much of Europe, led the US in government spending to end the Great Depression, and that the US recovery responded to the massive demand for US goods by strong economic growth starting in '39. If this is what you refer to, I accept that....but note that it was still consistent with Keynesian theory. Also, one would note that FDR did a lot to restore trust in banking in the first 100 days, which had a psychological effect...with people trusting banks more after the bank holiday than before. It is theoretically possible that this is coincidence, but unlikely. Also note, that the largest rise in GDP coincided with the largest government outlay...mostly on "wasteful" spending. Well, at least from economic terms, tanks and air craft carriers are not useful economic capital. This was all accomplished without massive inflation, which you're theory predicts. It's true that there were wage and price controls during the war, but they were taken off after the war, and the total inflation and economic growth from say '40 to '50 was significant. Fast forward to the late '70s and '80s. Monetary theory says that the Fed's tightening of the monetary supply caused both the big recession of '82 and the lowering of inflation. Your theory would argue that the increase in wasteful government spending in the '80s would increase inflation. Now, let's go to the '90s. We know that federal deficits tend to be inflationary, and Greenspan worried about this. He also worried about loosening credit, until Clinton convinced him that the rise in productivity would result in total goods and services rising to match the increase in the supply of money. If money increases no faster than goods and services, there is no inflation. If it rises faster, there is inflation. If it rises slower, there is deflation. (you have to include velocity too). This is real standard stuff...remember I'm related to an economist. :-) So, it is true that I didn't chase down every rabbit hole. But, in engineering, big causes correlating with big effects is a darned good bet. Your theory needs unseen small causes with big effects that coincidently coincide with data to explain your inconsistency. But, given that, I can prove nearly any theory right.
