When talking about that polarization, it feels irresponsible not to mention the role of Fox News and companies like Sinclair Broadcast Group in pushing 24/7 fear-and-hate programming nationwide, partly to continuously promote right-wing politics, partly because angry and scared people are more vulnerable to ads like "use all your money to buy gold from us because it's the only safe investment".
they are just an economic actor maximising profit by exploiting a low-regulation environment where anything can be monetised even hate (again “freedom”)
