You comment about the smartest alphas filling their organizations with competent betas makes me ponder whether that’s how Mycroft got his job in the first place… and then took over.

Okay, here’s my headcanon on Mycroft’s job, which doesn’t really change regardless of whether it’s omegaverse or not.  Mycroft got his job through sheer competence, because he can do something that no one else can do.  I’m pretty sure it’s the same job as it was in the stories—a kind of super-analyst, able to see connections between tiny details and things going on in different parts of the government.  He is in fact something that we only recently came up with a name for:  a business intelligence analyst.  He compiles and studies the data, and generates reports on what he sees in it.  He is unique, however—and uniquely terrifying—in that the job ordinarily requires all that unfathomable mass of data to be stored in computers and databases.  For Mycroft, it’s in his head.

In a sense, it IS a ‘minor’ position—he does not himself set policy or make strategic decisions for the British government as a whole or even for any part of it.  He simply provides information to those who do.  But he has been given the power and contacts he needs to access the information he needs and bridge the gaps he sees.  Thus, Sherlock’s claim that he ‘is’ the British government.  Mycroft is the living, thinking database at the heart of the realm.

That job doesn’t exist without him.  It didn’t exist before him, and when he goes, it will cease to exist because there’ll be no one else who can do it.  But while he’s there, by god, the government runs about 1000% more efficiently.
