He's a political pundit. Part of his job is, at all times, to be entertaining and attention-grabbing. That means his appeal and success are directly tied to how abrasive he sounds at any given time. That's the unavoidable pitfall of the profession, and it's been true since long before the internet and even before television.
Punditry content is not for me personally, but I do think it is filling a niche. Especially as very very few online American content creators have been willing to engage with politics directly.
Funny when here in Belgium, the government put a couple decades ago a cap on the number of doctors who were allowed to graduate medical school (numerus clausus). The goal is to reduce the number of doctors to pay for (with the support of existing doctors who want less competition).
The predictable result of artificial scarcity? I live a major city and if I want an appointment with any specialist it's a 6+ months delay or a 1-2 months if you can justify a daytrip to Brussels. This is having real tangible impacts on quality of care.
Obviously I would not trade my healthcare system for the American one but let's not pretend that money and greed aren't factors.
