@JPB,
I agree with your analysis by 100%. We elect them into office without understanding the consequences for extremist views.
We were in recovery mode when the tea party won elections, because Americans do not understand that Great Recessions are not solved overnight.
Americans also do not understand basic economics; austerity programs during economic recessions only exacerbates problems.
The fundamentals of the American economy is relatively strong, because our economy is based on diversity in the production of goods and services.
We just need to push it along with more government spending to improve our infrastructure and education. When we continue to constrict government spending in one bell swoop (one debt ceiling vote), most of which was approved through both democratic and republican control in Washington DC during decades of give and take, it becomes impossible for our country to survive.
The fact that many countries were confident in purchasing US Treasuries was based on the strength of our economy; that we would always pay on our obligations - on the bonds.
That's now all changed, and what has happened to Greece will now be reflected in the higher cost of borrowing in our country. That only creates a bigger handicap for our economy with higher interest, and instability in the bond markets.
This will also impact our economy in many negative ways - at a time when we were slowly digging out of the Great Recession.
