If you are worrying about the US 'shutdown', or debt ceiling or 'default', don't. The mainstream media understands little how the mechanisms actually work, and all the political posturing leads to the phoney headlines you see. The truth is that the US cannot legally default as long as they have cash in the till. And they will have cash in the till for many years yet, as they take in hundreds of billions monthly (even when 'shut down').
The 14th amendment to the US constitution compels the federal government to pay its debts and interest first. What this means is that if they hit the debt ceiling, they will have to cut government spending, not forego paying debts. Under the current government 'sequester', and with the shutdown, they have already curtailed spending about 15% or so. They will have to scale back another 10% if they hit the debt ceiling. Then they could only spend what was coming in. In your house it's called 'living within our means'.
If you are really bored and want the info on why Social Security spending will not be halted through these troubles, message me and I"ll give you the goods. But consider that it's similar issues that prevent this.
The key fight is really about discretionary programs (including Obamacare), and using new debt to pay for this.
NOW KEEP CALM AND CARRY ON
