> That sounds great in theory, but the problem is that many of these leadership roles if not elected directly are nominated by the president and therefore they are political in nature and those politics can flow down through the organization.
That could be changed though. It's not how it works here in the UK. The ministers in charge of departments are political appointments, but we also have a substantial politically neutral civil service with lots of headroom for career advancement. (politically neutral to the point that you are not allowed to publically express your political opinions - posting them on social media could be a firing offence)
The US also has an apolitical civil service infrastructure, just not at the top of these agencies. And it is the leadership that people refer to when they worry about the revolving door. No one cares when some low or midlevel USPS worker goes to work for FedEx, they care when the former FCC chair Kevin Martin is tapped to head up Facebook's US Public Policy.
