Generalize much? A PhD might be able to help with that.
I knew a guy who had a doctorate in linguistics. People kept asking him “Does this look inflected to you?”
That’s nice, but prefer my meals to go only one direction.
Given the attitude of the OP, I don’t think he needs to worry about the boss, except when the boss tells him to put more fries in the basket.
And everyone knows the degrees go
Bull Shit

Or a consumer of Russian troll propaganda?
The question is silly, and springs directly from the ongoing cultural wars. Surprising so many here are sounding off, as if this were a real topic of discussion…
No.

In general, no, though it depends on the context and situation. If you’re a consultant, for instance, it’s perfectly fine to put your degrees and also elected memberships in recognized academic societies and the like on your business card. But to flaunt an advanced degree at every opportunity is something that, to me, raises a red flag that you may be dealing with an asshole, but worse, you may be dealing with a fraud.
In my travels through the realm of climate change information and denialism, for instance, I’ve found thatlegitimate sources of information credit the contributors and often cite their academic affiliations, but it’s just assumed that if they’re doing research at accredited institutions they have PhDs, so it’s rather redundant to keep reminding everyone. It’s kind like if I signed off every post with “Wolfpup, certified human, not actually a juvenile canine”. Contrast that with this fraud, who not only prominently displays “PhD” after his name on his worthless lying blog, but even the URL is his name with “Dr” prefixed in front of it. That sort of ostentatious preening is usually a tip-off that you’re about to be treated to some really high-octane bullshit, and that site does not disappoint!
He speaks to the gods, and so may any man, but does she listen? 
I have a relative who was a research physicist before he went into finance. He’s not arrogant, but but having a PhD in nuclear physics stands him in good stead when in a room full of pricks who think they are smart because they made their first million before they were 25.
My first university valued persons according to their academic merit. It wasn’t all good: if you failed to learn something, it was because you were a lower level of being. But it wasn’t all bad either: I never knew the lecturers to get their facts wrong at all, which is more difficult than it sounds, even when teaching undergraduates.
Not me. I don’t put my odds’n’ends from different universités and professional qualifications / recognitions on cards, letters or e-mails.
Just “Northern Piper, Counsel.” That’s all the client needs.
ETA: don’t have a PhD.
Pretty much standard if you are talking about emails from their work/university account. Many of my colleagues include it in their automatic signature in their emails, so it’s included even in emails they send to me. Of course, since a great deal of their correspondence is related to their professional expertise, there’s good reason to include it.
It’s different for your personal email account. I don’t know anyone who signs personal emails like that.
At work, or in other professional settings, I’m called “Dr. Colibri,” because that’s the standard practice. For people I work with closely, I usually ask them to call me by my first name. But some still insist on calling me “Dr. Firstname.”
Dat wuz a joke.
Depends where you are. Germany is notorious for the listing of academic qualifications. It’s a cultural thing, and the academics are the worst for this, but you see enough business cards with a string of letters after the person’s name. Elsewhere in much of Europe, outside the academic world it is thought rather pretentious to do that.
I have a degree, but I only list it on my CV and only because potential clients expect that I have some sort of qualification.
More or less arrogant? Maybe slightly more, on average, but I have probably encountered more arrogance overall from the clearly unlettered.
scarface54345, do you have any personal stories of someone with a Ph.D. acting arrogant, trying to come across as a god, or telling someone to get out of their classroom? Not something you read, but something that happened to you personally. If you don’t, then all you have is one passage in something you read that says this. Why do you think that that proves anything? For any given type of person, if you read widely enough, you’ll eventually find some passage in some piece of writing that criticizes that type of person. This can mean either that (1) you can’t trust anyone whatsoever or (2) you should be reading much more widely and comparing lots of different pieces of writing. To make any statement, you need lots of pieces of evidence, not just one piece of criticism in one piece of writing.
As Brayne Ded says, there is more arrogance from people who don’t know anything about a subject than there is from people who a reasonable amount about a subject. Do you know about the Dunning-Kruger effect? Take a look at the Wikipedia entry on it:
Here is where even the lowliest, lamest, laziest trolls can dine like kings. Help yourself to the buffet.
Also do even if you do have a personal anecdote of a PhD who behaved badly, how do you know that his bad behavior was related to his having a PhD. If a person who ran into my car had green eyes, am I justified saying, "Ever notice how people with green eyes are always such bad drivers. "
When I worked in customer service, by far the biggest assholes were always lawyers.
How did I know they were lawyers? Because they would take great pains to tell me they were lawyers and thus use that as a basis to (wrongly) contradict one of our policies, or use it as a threat to try to leverage to get their way. So a JD (or possibly JSD), not a PhD.
The good lawyers (of which there are plenty) never did these things so I only knew them as regular customers.
I’ve met plenty of “doctors of this 'n that”. Take them out of that very narrow specialized field of study, and they are no different from and no better than anyone else.
Unfortunately, the press, and people in general, give them authority and deference in ALL fields. That’s stupid.
