To a first approximation, the globalization and technology driven collapse of the white non-college male, channeled by AM talk radio.
AM Talk radio which exists so advertisers can sell things to its audience.

Advertisers who do business with Sean Hannity include the U.S. Concealed Carry Association, Mozy, Tax Defense Partners, Legal Zoom and the Vermont Teddy Bear Company.
There you go. It’s all the fault of the Vermont Teddy Bear Company.
(Seriously, who really funds Sean Hannity?)
