"Better tech" is a double edged sword though because it can result in more efficient output but also more demand for output. The military was a lot cheaper in absolute terms before the technology existed to build nuclear powered aircraft carriers. But if you want to maintain a capable military you need to build nuclear powered aircraft carriers not just equip your troops with more efficiently made muskets. While certain specific functions of government can and probably do get more efficient as technology progresses, the demand for new functions or more of existing functions goes up. You didn't need an FAA before air travel and you needed less FAA when there was less air travel, for example.
