The idea that conspiracies could thrive under economic stress doesn't even occur..
But there are a lot of other factors in the problem and making it an economic issue really obscures some of the more important factors.
Intellectual laziness, idle brains, idle hands, toxic memes and bad actors making bad use of them.

They drink from the cup of nonsense to excess.
There should always be room for drinking from the cup of nonsense but too much and its difficult to be useful to yourself and your family.
