The bottom line is that the Repubs are largely responsible for our current situation yet they won't take any responsibity for it and in fact want to double down (and there is a specific reason for this)
Republicans don't like the government and don't like government spending that benefits our country (infrastructure, education, etc..) or the majority of the citizens (social security, medicare, etc..)
Republicans represent large corporations and the people who run them and that's it.
Rich people don't need anything from the government other than a low or non-existent tax rate and no restrictions on business of any kind so don't expect them to ever be in favor on anything that benefits 95% of the citizens or 100% of the common good
The Republicans wet dream is to destroy the government or to get it a level where they can drown it in a bathtub (this is literally how they imagine it in their idealized world).
Old School Republicans used to hide their intentions but this new school of Tea Baggers (who are really running the show in Washington and in many states) are either too stupid or just can't be bothered in hiding their true agenda
The current debt issue was intentionally manufactured by the Republicans
