Why Does Elon Musk Still Have a Security Clearance?

"To big to fail" just means "should be held in the public trust"
Musk is a constituent part of the US military-intelligence-propaganda-industrial complex, as many US oligarchs are. Just thinking of tech oligarchs alone, off the top of my head, other such members are Andreessen, Bezos, Brin, Ellison, Schmidt, Thiel, and Zuckerberg.
The oligarchs and the government aren’t separate things, they’re an integrated system.
Thank you for the link, I hadn't seen that study
