You miss the big picture. The military industrial complex is just the trophy wife of the banks.
The secret sauce of capitalism is public debt backing private wealth. The wars are just a way to make it go away, so more can be borrowed.
As executive and regulatory function, government is analogous to the central nervous system, while money and banking mirror blood and the circulation system.
We've evolved to the point of understanding government is a public utility, but yet to realize the same principle applies to banking.
Which has given banking the upper hand, as they are not as subject to oversight and don't have to plan around election cycles.
Consequently they have hollowed out government, leaving a bunch of flunkies, prostitutes and sociopaths filling the roles, whose only real function is to create debt.
