Talk radio...as in Limbaugh, Savage and others on the hard right...has NEVER been about informing, educating, or even thoughtful advocacy; no, it's all about business, as in earning revenue through a constant stream of bitter sound bite mental candy to people so that they will buy stuff from advertisers. It becomes a kind of bizarre mental arms race into the gutter, feeding conspiracy and fostering an attitude of "it's the fault of _________ you are not getting ahead", where the blank could be filled by everything from ACORN to Obama to Black Lives Matter to fluoride in drinking water, all in the name of increasing advertising revenues. Who needs a thought provoking discussion when you can simply point fingers and call names?
For the record, having listened to Limbaugh over the years (from time to time) and having read some of his work, I'm reasonably convinced that even he doesn't believe half the stuff he says, but he does know how to generate ad revenue. Hillbilly heroin abuse may have destroyed his hearing, but it's done nothing to dull his keen business sense.
