The idea that you have those at top of military and top of defense contractors working to keep their influence high… military demanding ever increasing budgets and new weapons, vehicles, etc. while the defense contractors making them lobby Congress to help the cause.

And you’ll often see high ranking military or elected officials go to work for defense contractors as lobbyists or other high paid positions when they want higher income, so their work while in government is often looking forward to personal enrichment by doing favors vs. actual best interests of military/country.
