> with a spending limit... The reason a significant portion of the US government is shut down is because they literally have no money to spend because congress hasn't raised the debt ceiling to allow the government to borrow more money. So the 'spending limit' you mention would have been $0.00 the moment the shutdown happened. Probably a better solution is to no longer run the government with a spending deficit.
