The Tea Party/GOP has now revealed it has no concern for the well-being of US workers, the US economy, health care for Americans or whether this country retains its place as a trusted economy that can be expected to act with its rational self-interest in mind.
Nope. They're willing to destroy all that--and cause heedless suffering to millions of Americans, from the federal workers thrown out of work to the repercussive echoes of the shutdown throughout communities across the country. They now intend to add the debt ceiling to the shutdown to put more pressure on the country's wounds in order to get their petulant way.
This anarchic extremism is far from their duties as representatives of the government they are trying to destroy: they appear to be willing to sacrifice anything and anybody to keep themselves (and the ultra-rich people and corporations who are their primary funders) in power.
