Something, something, military industrial complex. Something, something lobbyists. Explanation achieved.
I think you forgot one other reason.
Stupid, stupid fucking Republican imbeciles that don't get it that their votes continuously elect politicians, that year after year after fucking year work on keeping this country in the Dark Ages (to keep being re-elected?), being it the refusal to accept the reality of global warming for instance, or that Creationism is still a viable option as to why the human race exists, or that a LGBT community is unacceptable, and marriage between two people that deeply love each other, should be banned because they don't approve of it, that a woman doesn't has the right to make her own decisions about her life, that will affect her existence forever, that think because they can mange to keep their measly, little bank accounts balanced ( more than likely with some government aid ( God I hope SS and Medicare goes bankrupt just when they retire)), that a global economy should do the same That thinks that a strong military trumps every single appropriation made by the government, it being college loans, or as mentioned originally, fixing the fucked up infrastructure of this country (provide jobs at the same time ?), and whereas Bolivia has better roads and a more modern rail system than us, or aid to school systems ( they never needed a diploma to slop the pigs, or to shuck the corn), to provide more assistance to police departments nationally, like body cameras,(that might help to stop cities being burnt fucking down), that can't be afforded now by most departments to make the asshole cops ( how many psycho cops have you met) at least to think twice before beating the shit out of someone, or using them for target practice.
To me all the things that I have just mentioned (and there are a couple of dozen more that I haven't) will be a legacy of the drastic shift to Conservatism that this country has taken in the last 2 years, mainly in my opinion due to the unending assault on the elected President of the United States, by the Republican party ( they don't like blacks?), who if Obama wiped his ass with Charmin, they would complain that it was something that only Muslim un-Americans would do, that true Americans use Scott's.
Time out for a bone break, my fingers are tired, and all that are reading this diatribe probably also need a break. Peace (except if your a Republican, then go fuck yourself)
