Take Germany for instance — when Annegret Kramp-Karrenbauer was defense minister, she tried to reform the Bundeswehr Procurement Office with little success. Currently, over 11,000 employees work for the agency — an enormous increase since the Cold War, when considerably more material was being procured by considerably fewer employees. In 2010, the procurement office was already heavily criticized for its inefficiency and large size, with its 8,500 employees — and the situation still seems dire.
That is a wild number of people who are not getting anything done and who then become a pension burden on the public budget.
