<prompt> Human: Ive recently taken an Econ class, and learned that when inflation is so high, cash money is realistically worthless I mean, at least until the dollar raises. While that lesson was something I already knew, I learned a deeper lesson: when paper money is worthless such as in the great depression, people resort to trading goods and services in exchange for other said goods and services. My question is what is a good commodity that will always be worth something to someone, and is small and easily transported, or hell, not even necessarily small. I know that diversification is a key method to always surviving some crash or another, but I would like to invest in such commodities as a diversification as well, gold and jewels are kind of obvious, even though gold is possibly questionable. I read somewhere about Krugerrands being viable since theyre 1 troy oz each of gold. Anyone have any solid ideas?Assistant: Why would a depression and inflation go together?Human: Well, I mean, there was massive inflation during the Great Depression, was there not?  <response>: No, there was deflation after demand for goods dropped drastically after WWI. The only period of high inflation not hyperinflation was in the 1970s.
