Of course, the US needs a real parliament where failing to pass a budget bill would result in a dissolution of parliament and new elections.
On the other hand, given how fractious US politics are, the US would go through more governments than Italy.
No other country shuts down its government in the same way the U.S. does.
That's not to say that other nations don't have budgetary disagreements and worse. They do. But "for most of the world, a government shutdown is very bad news — the result of revolution, invasion, or disaster," says Anthony Zurcher at BBC News. Seriously, "even in the middle of its ongoing civil war, the Syrian government has continued to pay its bills and workers' wages."
Syria's not alone. "Countries like Pakistan and Colombia have had civil wars, coups, financial crises, even defaults but never a government shutdown," says Erik Voeten at The Washington Post's Monkey Cage blog.
