Without technology, say bye bye to at least 6 billion people. We've turned the earth into a machine for sustaining life. It's clear that we need people who understand how the machine and its parts work, well enough to keep it running.
But those people don't necessarily need to be gods or kings. In fact gods and kings seem to be exquisitely bad at it.
A relative of mine was a senior operator at a nuclear power plant, now retired. He deeply understood how to keep the plant running, and was compensated nicely for it, but he didn't presume to know better than the next person how to keep society running. He didn't aspire to be a king.
"Rich people bad" seems like a straw man. I think there's a fairly widespread perception that letting some people become rich enough to turn themselves into gods or kings is worth reconsidering.
