Regardless of personal beliefs, there's the other issues here. First, what does "massive growth in government" even mean? Do you mean in government meddling in people's personal lives, like restricting bodily autonomy for women or banning books? Yes, I agree. Do you mean in government spending? Sure, agreed, the numbers agree. But you seems to be referring to some other kinda vaguely defined concept of like... government bureaucratic-ness? I'm not really sure what you mean and how to measure what you mean.
The second issue is your overall thesis seems to be "the government is inefficient," which is fine to say and to criticize, it certainly is inefficient by many measures, but I feel like you're hinting at some kind of alternative that I can't possibly guess at. Usually these discussions take two routes: the capitalist one, wherein you argue that private industry is more efficient, which even if we accept that efficiency is the only valid measure of how we should choose to do things (amazon builds road faster and cheaper than government: then puts a toll on it so only the rich are allowed to use it. this is bad), is probably not true[0] or possibly the opposite of the truth. Maybe you're more anarchist in your leanings, in which case you're arguing for more distributed and local management of these kinds of services? That could be a really interesting conversation, is that what you're suggesting?
