I'm not sure how people still legitimately believe, or even pretend there is no "deep state" or "conspiracies" happening in and around all our elected and appointed officials.
Some people just can't grasp it because it disrupts their sense of what the world should be, especially in America. The "deep state" has turned the term "conspiracy theory" into something dirty and shameful - that way all "conspiracy theorists" can be lumped into one neat little group of crazies.
Americans are the best at sticking our heads in the sand to protect our worldviews.
To act like Trump (or anyone else) is crazy for believing that there are (and were) individuals within our executive, legislative, and judicial branches who have conspired together to maliciously serve themselves and line their pockets over serving the American people is bonkers to me - it's childish wishful thinking - or the Dunning-Kruger effect at work - or possibly just a simple groupthink phenomenon.
You can lead a horse to water, but you can't make it drink...
Or think. Trump and his cabinet/admin are Establishment, too, almost always are. Kurt Nimmo and Chuck Baldwin detailed around 26 CFR members & Bilderberg associates in Trump's cabinet:

I absolutely agree that Trump is somewhat of an insider (more so in the financial world than the political one)... Is he perfect? No. Was he my first choice? Hell no. Was he a better choice than HRC? Absolutely. But, there is a reason the entire RNC refused to back Trump - he got elected without them which is unprecedented.
I believe that reason was because they all knew he was completely independent and out of their reach of influence - he cannot be bought by all the lobbying vultures who care nothing about what their crap "policies" do to the well-being of society. And, in my opinion, I'd rather have someone in the oval office who is making decisions that aren't based off what some stupid company's lobbyist is pushing.
And as far as his cabinet, look who he had to choose from. There isn't anyone in Washington who isn't corrupt in some fashion. Not to mention that lots of those people were probably positioned there to sabotage the entire administration, and several have tried.
