Concisely, more people should be worried about this Government shutdown. There could be some serious ripple effects!
What’s happened? The budget, or ‘supply’ has been blocked.
Basically, the Americans have the same Bicameral (two Houses of Parliament, Congress and the Senate) system we do, and Legislation has to pass both houses. The budget is a piece of legislation just like any other, most political parties, particularly in Australia, will vote supply through without much fuss, because it’s money for the country to run on.
