I was thinking progressively, but if global economics do go that foul, well, that's why a good portion of my investment portfolio is in blued steel, copper jacketed lead, a cadre of like minded and capable partners, and 40 acres out somewhere not on a map.

Besides, even in desperate times, there's a market for some items. Money may be worthless, but as long as there are resources to be collected, processed and distributed, there will be trade of one form or another. It pays to diversify a little.
