Hundreds of thousands of protesters are on the streets of Madrid tonight. Their message to their leaders is that not only is austerity not working, but that it's making things worse.
That message is supported by dreadful economic figures today that show accelerating recession in southern Europe and big falls in manufacturing output.
All the focus, certainly in Brussels and Berlin, is on saving the Euro and avoiding the catastrophe that they think would follow a collapse of the currency.
But leaders in cities like Madrid have to see what their people are doing and saying. Much more of protests like today's, and this country could become ungovernable.
