Howard Ruff, author and “conservative” economist.
I had a copy of How to Prosper During the Coming Bad Years when I was a boy. The young me thought Ruff made a lot of sense, but I really wasn’t in a position as a lad to take any action on his recommendations. In retrospect, it doesn’t seem like much of what he predicted ever came true, so maybe that was for the better.
I would like to see an objective analysis of how his recommendations performed against the market, but I don’t have the time or data to do that. Maybe someone else will.
