Pardon me, but I am sorry to say I find these reasons you state are economically dubious and factually devoid of substance. Government HAS (or should have) shit to do with the economy in any direct fashion, EXCEPT how it currently interferes WITH self same, UNLESS you are considering the Military/Industrial complex essential to a healthy American economy.
I do not.
I think it signifies a serious susceptibility to propaganda and a kind of mental illness generated by rote proliferation of insecurities by media in the vast majority of an distracted, ill-informed and morally misled population.
The real reasons the economy is foundering is the direction our government had led the nation through treaties and acquiescence to international influences regarding durable goods, manufacturing, industry and exportation in the last 50 years. Crap is now King in America. Cheap, foreign made, throw-away manufactured goods don't equate with a truly healthy economic "here at home" scenario.
America doesn't even HAVE the EXPORTS it used to. Nor does it even have as many single owner businesses as it once did. The largest category today is softwares as intellectual properties and services, not the manufacture of durable goods, which hardly even factor in. Except as distribution hubs there are no large scale handlers of manufactured durable goods.
As a result, the better paying jobs of skilled laborers have left the country due to the corporate need for profitability for the shareholders over the simple need of earning a living on the local level. The immense wholesale buying power of a corporation can manipulate prices out of the range of the average, single owner retailer and these corps average UP with volume sales, generating poor wages, and consolidated shipping and distribution hubs and increased bottomline profitability. PROFITABILITY??? Over the Right to life, liberty and the pursuit of happiness???
Excuse me, but that's BULLSHIT and part and parcel to a financial and economic cartel that ULTIMATELY STEALS EVERY WORTHWHILE THING from the American people in ways so subtle, most never even connect the dots between "cheap money", "inflationary monetary policy", aggressive, regulative restriction on job creation, subsequent job loss during an inflationary or recessionary period, falling wages, and the demise of the overall health of the nation by the manipulation by the regulatory powers of a government with a certain CLEAR AND OBVIOUS AGENDA to first, exploit, vampirize and then break the economy via contraction and expansion of the "money supply".
How's that for a run-on sentence?
The national debt is an odious debt of the Corporate government, not of the People.
