Bureaucracy does tend towards bloat and failure, both in the private or public sectors. I can quibble with your examples (I don't think they're appropriate), but even if we allow that they are indeed successes, for each one I can find a handful of very consequential failures (DoD, VHA, HUD, etc). Consider especially where government is tasked with providing a service, instead of shuffling money around to pay for it. This is admittedly a US-centric perspective, but why should I want to trade our poor governance for, say, European institutions with their attendant sclerosis?
