Ray Dalio/ Global Market slow down

Ray Dalio suggested that the current debt cycle mirrors that of the debt cycle and political climate of the mid 1930s (protectionist policies, tariff wars, and etc) and that the global market is slowing down. So i'm wondering can good investment still be found despite the current slow down ?

Thank you for your forum post, Rodeler!

A lot of people have suggested similar theories. But what Graham himself wrote was to always stay invested, even during times of war or periods of extreme uncertainty.
