There are state-run organisations that are fairly efficient - the UK NHS, which is pretty much the epitome of a large socialistic undertaking, is actually pretty economically efficient. The fact that it has problems being largely because we don't spend much money on it, not because it isn't efficient in using what money we give it (at least in comparison with other healthcare systems).
