Not sociopaths, but sociopathic careers, as a term of condemnation.
And a lot of people light up the BS detector like they wouldn't believe.
Loosely put, the majority of them fit the stereotype who think that everyone is ruthlessly self-interested, but they don't think of it as ruthless, and they think of themselves and the others as (in Bay Area stereotype, for example) nice and cheerful and progressive. Their vague awareness not to be crass about it, according to the social conventions they've gotten in their peer groups thus far, is insufficient to hide it.
But others of them think they are "the alpha", and believe themselves to be more aggressive than others, and more meritorious. Yet, of the ones I've noticed (and this might be why I noticed them), they're not as smart as they think they are, when they try to manipulate, and don't know how to fake being someone they aren't. They instead lean on family money and connections, alliances with power structures, gaming, underhandedness, aggressiveness, etc.
Though I knew one very smart and very charismatic ruthless person, who was smart enough to avoid the tells, so I know they exist. One way of describing it is that they could play parts of different personalities, thinking of things the personality would think of, as needed for different audiences. Once they started tipping their hand, it was too late to stop them, and society is significantly worse for it. I speculate that these people are a very small minority, because I think otherwise they would have taken over more positions of power. Yet we can see that many powerful tech companies are headed by people who obviously do not have these qualities of brains, charisma, and empathy. Maybe the non-ruthless ones become great writers, actors, and teachers instead.
