Not that any of this is incorrect, but there are two important bits of context to add here:

-Not all DoD hires are for the purpose of lobbying. A lot of the time it’s just because they already have the TS/SCI clearance which is necessary for working on servers in the government.

Of course not. Only the managers are for lobying. ( which is corruption with a differrent name). It does help to hire people which can influence the government.
