Good point. My dad always said get a job in an industry that deals with something everyone needs. He is an engineer; was in natural gas.
I was in grocery distribution and warehousing.

Commodities are a different category. While I was in food distribution, the company had an absolute rule that the buyers could not speculate on commodities, not even as a hedge. We bought finished product not raw material.
I don't see Berkshire Hathaway in speculative assets. Strictly long term investments. Hmm. It does own insurance companies.
