The USA has a huge military budget because:
 it values its freedom and independence
 it values its allies and trade routes
 it costs the USA a lot more to get any measure of military might since it does not have a conscripted military and its materiel is not made by government suppliers.
The USA has a huge military budget because:
 it has whipped it's population, and that of a significant portion of the worlds population, into a frenzy of fear and paranoia, by maintaining a permanent war status since the end of WWII. Whether hot or cold, the USA has waged war against non-enemies, aggressively supporting brutal dictatorships around, killing millions in defence of "freedom and democracy" around the world. The USA as "protector" of the "free world" has been holding the human species hostage to the possibility of imminent extinction via nuclear weapons for nearly 70 years now. This in the name of valuing its freedom and independence.
 it has decided that the best social control mechanism for social pacification is to provide the lowest possible cost for goods and promoted consumerism as ersatz status symbols for a largely disenfranchised permanent underclass. In order to secure such cheap access to goods, the USA must dominate all world trade and be able to dictate prices for resources, resource extraction, production and distribution. This in the name of valuing its allies and trade routes.
 it spends a lot less money for the size of our military than any other country would for a similarly sized and scaled military because 18 year-old's with no prospects always form a cheap labor pool( "sold" as in soldier, comes from Roman Latin, daily wage-worker), particularly if one can convince them that they are serving their country men in the name of noble goals and values like "freedom and democracy". And because military production in the USA has always been "dual-purpose", a civilian feel-good, while producing weapons of mass destruction.
The USA has co-opted a tremendously large section of it's so-called private market for dual-purpose: production of disposable goods, while supplying the worlds largest military with an endless production line of "goods", of which no good can ever come. Most major manufacturing firms in the USA would not be economically viable if it were not for this arrangement. Boeing could never make it solely producing commercial air-liners, the market for such is not large enough, but if the Pentagon needs x number of fighter jets, missiles and rockets every year, which must be constantly restocked, due to usage in wars or due to degradation from not ever being used, they can show a profit for their civilian production lines. The same is, and has always been, true for GM, Ford, GE, etc.
The USA has not, historically, HAD a "health service" because we traditionally left health to the people themselves, the private sectore, and communities and states (The US Constitution says nothing about healthcare, and it explicitly says that anything it does not assign to the federal government belongs to the people and to the states)
The USA has not, historically, HAD a health service, because immiseration is a constitutive part of maintaining an exploitable permanent underclass. During the first 250 years of American history, surplus value, ie. profit, was made primarily by either a) stealing the indigenous peoples lands or b) exploiting "free labor", ie. slavery. Following the civil war profit has largely been made by exploiting those born into inter-generational poverty, both here and around the world. The majority of Europeans who immigrated to the USA during the first 150 years of colonization were debt-prisoners, ie. the then european permanent underclass. The USA has proudly cultivated cultural identities for the permanent underclass, going back almost 350 years, nowadays we call them "rednecks", the "n-word", and "mehicans".
The constitution, written for the most part by by the 18th century 1%, actually went to lengths to prevent the existence of a standing army. The USA has been violating it's own constitution every day for nearly 70 years now by maintaining the largest scale military ever seen in world history in direct opposition to our founders intents. With a media hell-bent on scaring the bejesus out of everyone 24/7, covert intelligence services, dedicated primarily to propagating domestic propaganda(be scared, be very scared), and brutal police forces, who routinely terrorize, denigrate and humiliate our permanent underclass, we have held our population in line through domestic terror, knee-jerk reactionary patriotism, dog-whistle ethnic discrimination, and cultural envy as a function of permanently denying the permanent underclass of the USA access to the "freedoms" and "democracy", which supposedly are those things that make America all so great.
What really hurts me sometimes is that there’s not a lot of consciousness in their music. There could be a whole lot more. Rapping is communicating-it should be an instrument for our liberation. We don’t have time to talk about being players and hustlers and gangsters. We didn’t come off of the slave ships that way. We need to become proud Africans again and stop running around in Shirley Temple curls talkin’ ‘bout how we’re pimps and players. A lot of the symbols that are in rap records and videos are indications of decadent consumerism and in a very real sense, those gold chains, hundred-dollar sneakers and T-shirts with a designer’s name on it underline how much they’ve become enslaved by the consumer mentality in the United States-consumer slaves.
Don't be deceived when they tell you things are better now. Even if there's no poverty to be seen because the poverty's been hidden. Even if you ever got more wages and could afford to buy more of these new and useless goods which industries foist on you and even if it seems to you that you never had so much, that is only the slogan of those who still have much more than you. Don't be taken in when they paternally pat you on the shoulder and say that there's no inequality worth speaking of and no more reason to fight because if you believe them they will be completely in charge in their marble homes and granite banks from which they rob the people of the world under the pretence of bringing them culture. Watch out, for as soon as it pleases them they'll send you out to protect their gold in wars whose weapons, rapidly developed by servile scientists, will become more and more deadly until they can with a flick of the finger tear a million of you to pieces.
The trick isn't that you have no freedom, the trick is that you think that is freedom. All your fighting is for... consumer products.
The ideals of homo faber, the fabricator of the world, which are permanence, stability, and durability, have been sacrificed to abundance, the ideal of the animal laborans."The Human Condition"
The relatively new trouble with mass society is perhaps even more serious, but not because of the masses themselves, but because this society is essentially a consumers’ society where leisure time is used no longer for self-perfection or acquisition of more social status, but for more and more consumption and more and more entertainment… To believe that such a society will become more “cultured” as time goes on and education has done its work, is, I think, a fatal mistake. The point is that a consumers’ society cannot possibly know how to take care of a world and the things which belong exclusively to the space of worldly appearances, because its central attitude toward all objects, the attitude of consumption, spells ruin to everything it touches."Between Past and Future"
If this is where smartphones peak - usable for two and a bit years - we need to take ourselves out to the car park for a strong conversation.
All over the place, from the popular culture to the propaganda system, there is constant pressure to make people feel that they are helpless, that the only role they can have is to ratify decisions and to consume.
People must be trained to desire, to want new things, even before the old have been entirely consumed. We must shape a new mentality in America, man's desires must overshadow his needs.
As long as the general population is passive, apathetic, diverted to consumerism or hatred of the vulnerable, then the powerful can do as they please, and those who survive will be left to contemplate the outcome.
Eventually, I realized that I had two choices. I could struggle for stupid stuff - for some trinkets and creature comforts - or I could make a choice to struggle for something that would make a better life for myself, my children and their children. You either work for yourself and your people or you work for the oppressor. Those are the two things that all young people in the United States have to decide, basically, and that they’re not going to participate in their own self-destruction.
We have to create culture, don't watch TV, don't read magazines, don't even listen to NPR. Create your own roadshow. The nexus of space and time where you are now is the most immediate sector of your universe, and if you're worrying about Michael Jackson or Bill Clinton or somebody else, then you are disempowered, you're giving it all away to icons, icons which are maintained by an electronic media so that you want to dress like X or have lips like Y. This is shit-brained, this kind of thinking. That is all cultural diversion, and what is real is you and your friends and your associations, your highs, your orgasms, your hopes, your plans, your fears. And we are told 'no', we're unimportant, we're peripheral. 'Get a degree, get a job, get a this, get a that.' And then you're a player, you don't want to even play in that game. You want to reclaim your mind and get it out of the hands of the cultural engineers who want to turn you into a half-baked moron consuming all this trash that's being manufactured out of the bones of a dying world.
[..] there's some line that divides games that are beneficial from games that are harmful. It's not really my business to draw that line today, I don't wanna try and convince you exactly what's beneficial and what's harmful, because again, that is up to the opinion of every designer and in fact the opinion of every player. But what I would like is for people to have an opinion about it. When people design a game to think about what that game is doing, and when people play a game to think about what that game is doing. And people don't, right now. They think about how it has cool graphics and a lot of levels and, like, they love the story about killing the bad guy. Which is not a very self-aware place to be standing when you're consuming something that affects your life for so many hours and therefore affects your mind for so many hours. And that bothers me. That makes me feel bad about being a game designer.
