How do you achieve this without prematurely alerting the American public?
Do you wildly inflate the budget beyond any reasonable ability to fund it? (Current accounts deficit, $1.5 Trillion)
Do you force the entitlement spending to consume the entire revenue stream while leaving essential functions to be funded on borrowed money? (Projected actual entitlement spending, including Obamacare, will outstrip tax revenue in <10 years)
Do you engage in opportunistic wars that consume materiel, without funding the replacement of said materiel, so that the military is weakened? (Libya?)
Do you push more people into government dependency by creating onerous hurdles to private sector hiring?
Do you collapse consumer confidence by overwhelming the banking system? (Housing bubble was a direct result of the policies of FNMA and FHLMC)
Do you increase food costs by mandating cropland be used for fuel supplies? (Ethanol)
Do you prohibit the exploration and exploitation of existing natural resources under our control? (Bans on Oil and Natural Gas exploration in the Gulf of Mexico (near shore) and ANWR)
What happens when the nations currently funding 40% of our current expenditures decide that they want a better return on their money? What happens if they do not buy our bonds? What happens if they decide to collect on a bond default by force?
What happens if the food shortages (and/or food price increases due to our inflated currency) foment hunger riots?
With these questions in mind, what are the chances that China will decide that it won't buy our bonds? If that happens, then we will have to increase the rate paid on our bonds to entice buyers. Doing so will explode expenditures on interest payments to service the debt and will cause a funding crisis in the short term (and a budgetary crisis for the foreseeable future). The cascade effect of this will be that the Dollar collapses as a currency.
I can see a whole lot of plausible scenarios unfolding if the Dollar collapses. None of them are good. Most of them involve military intervention at home (and not necessarily to 'repel boarders'), and martial law. Most of them involve the suspension of civil rights until the 'crisis' abates (if it ever does).
Most people are willing to give Baby Barack
What if Obama's actions really are malicious to the long-term success of the United States? What if ideology really does drive every action or inaction on his part? What if the results are intended? What then? Because the already-visible results of his policies, if intended, make him an enemy of the Constitution - Domestic variety.
Are you ready to face that reality?
