As a foreigner the whole government shutdown is a thing of wonder: how does it work exactly? For instance, is there no police anymore? How does Congress stay in session during a shutdown? Where does electricity in federal buildings come from if the Federal govt can't pay for it?
One thing to understand about the US is that it is actually a federation of states. Much of the day-to-day work happens at the state or local level, not at the federal level. Police, fire departments, emergency first responders mostly employed at that level, and when the federal government is involved, a lot of it is in doing some coordination between states, setting standards, funding for various programs, and so on…
It is a contrived emergency so the political parties can try to increase pressure to get pork through that they would not have otherwise in order to get the votes high enough to end the BS.
IMHO, the federal government should be entirely dissolved and the states should have a more loose confederation like the EU has. Federal law and over spending have gone too far. By overspending, I mean how the DoD decided to spend billions that it was not given by Congress. I don't mean any liberal vs conservative notion of how government should spend.
I know this is a pipe dream, but one way it could happen is through a "shutdown" that never stops.
