Yeah ruling juntas do need to "man the fields & factories" (1st order meatware), in order to produce and maintain those drones. Or nukes, or whatever "deciding factor beyond numbers" put them in power.

But they also need 2nd order meatware to support that 1st order: teachers, doctors, merchants… You need scientists to advance your technology against other militaries… You need leaders (3rd order) to keep the first two populations quiet and productive since that turns out to be more cost-effective than fear control through extermination…

Hell you need a certain level of genetic diversity so your own kids don't come out weird.

Give evolution a little more credit. The required number of humans for the in-group to be self-sustainable is definitely not billions, plus it's been shrinking with automation. But we are where we are for a reason – lots of alternative arrangements have been tried over millenia and found wanting.

"Keep my bunker + my drone factory and some farmers, kill the rest" leaves rulers with terrible quality of life (bad) and the next-door-junta taking over pretty quickly (also bad). It is a self-defeating, poor long-term strategy.

Automation tips the power balance further: fewer humans needed, more local autonomy. Which is, I suspect, why the ruling class are so terribly excited about AI, more so than some market valuations. Fewer pesky humans across all levels. Genetic diversity of bloodline remains the primary concern (unless you manage to live forever, which happens to be another evergreen of power ghouls).
