Ah, the study of economics...
It's obvious you have given this topic some thought and have some interesting conclusions.
Inflation or deflation?
I, imho, do not see the collapse as you do.
I do not believe we have unlimited food supplies and I am not a Malthusian. There's too much world demand for food and it will continue to grow. Populations are growing in many other countries and food stuffs will be needed.
The rest of the world may not need us nearly as much as it has in the past.
Oil will continue to rise and I see no factors to offset that in the near future. Again, other countries will continue grow as we may falter.
I think you are correct about stagflation...
The Fed will really have no choice but keep the money press humming to payoff U.S. debt and keep the Recession wolf from the door—it's already here.
If Obama is elected, imho, we will see public works projects to employ those who have lost employment in the private sector. A great military can only remain great if it's country is in good fiscal condition. I agree I our biggest gift is our innovation. Have a great day...
We see eye to eye on much. The other possible conclusion without collapse is perhaps equally worse: Attempt to socialize our way out of socialism until a major nation decides to attack us. That was the tale of the 1929 crash up until the Greatest Generation emerged by 1946.
