Right, so more efficiencies could free up resources to hire even more middle managers or administrative staff. It's only natural that well funded startups will have roles for "experience coordinator" or something. You think FAANG would have such a large headcount if they didn't have crazy margins?

There are some other tides working in the favor of bloated salaries and payrolls. One is the focus of "stakeholder capitalism". Most of the large companies are held by ETFs. The large banks that run the ETFs are less concerned about individual efficiencies of any one company (they own them all anyway), but are more interested in other things (green initiatives, social causes, etc). So the decisions being made at these companies are less about profit and more about servicing "stakeholders", be it their employees, the community, the environment. That's all fine, but it's difficult to track and hold executives responsible. A bloated staff is fine because you don't want to lay off employees. Or various money losing departments are okay because they're servicing the community.
