Somehow I missed this 7/25 Grantham interview with the excellent question-asker Charlie Rose.
I take long term forecasts of doom and gloom with a large grain of salt. Remember those dot-com forecasts of growth compounded to infinity? The sunny optimists and sackcloth and ashes types equally deserve skepticism. (Y2k, anyone?)
Recognize your bias, Bears.
That being said, JG is a brilliant thinker and I've read most of what he has published the last several years.
PS- the website above also has an interview with Crispin Odey who I've never seen interviewed before. Also worth a listen. I believe he mentored Hugh Hendry in his early years.
