So, friend, I ask you to stop and consider how you want people who encounter your lone voice in the wilderness to react. Assuming you care - perhaps you value having something to complain (and thus wish to ensure its continued existence) about more than you do persuading people that It Doesn't Have To Be This Way.
As a political minority, I am well aware that there are literally tens of millions of people who will dismiss my opinions without even pausing to think about them. That doesn't mean that I should stop having them, or stop expressing them in whatever way that pleases me.
I'm not exactly sure what you hope to accomplish by your responses. It almost sounds like you agree with the sentiment, but not the expression. If so, it is not a tad hypocritical to complain about how I am arranging my words rather than try to say it better yourself?
There's always going to be something to complain about. If not how the military-industrial complex is preventing the realization of peacetime prosperity, it might be how we have all this peacetime prosperity, but can't keep the mosquitoes from biting everyone at the picnic. If we run out of truly awful things to complain about, we can always complain about the merely annoying things. So I find your suggestion that complainers would actually prefer that the things they complain about not be fixed to be misguided.
I perhaps could say it better myself, but that's not my goal at this juncture.
Rent-seeking behavior seems intrinsic to human society, such that any group of people larger than a certain size will be forced to deal with it in one way or another.
At this point, nothing short of a constitutional amendment is likely to put a dent in the military industrial complex. And that's not happening any time soon.
Complaining about it helps me to not lose my sanity. And that's good, because without my sanity, I might do something like endorse an armed revolution to reduce the political and economic influence of the military in the U.S. See, as a sane person, I know that doesn't make any sense. There is a right way and a wrong way to fight fire with fire; that's the wrong way.
And it gets a dissenting opinion out there, on the off chance that someone might stray far enough from their own echo chamber to see it.
