One of the greatest passages in the Bible:

Then the Lord said to Cain, "Where is your brother Abel?"
"I know not," he replied. "Am I my brother’s keeper?"

When – and to what extent – is X responsible for Y?

German President Christian Wulff might be expected with his first name to know a thing or two about theology. And at a gathering of Nobel prize-winning economists he puts his own thoughts very directly:

Mr Wulff said Germany’s public debt has reached 83pc of GDP and asked who will “rescue the rescuers?” as the dominoes keep falling. “We Germans mustn’t allow an inflated sense of the strength of the rescuers to take hold,” he said.

“Solidarity is the core of the European Idea, but it is a misunderstanding to measure solidarity in terms of willingness to act as guarantor or to incur shared debts.

With whom would you be willing to take out a joint loan, or stand as guarantor? For your own children? Hopefully yes. For more distant relations it gets a bit more difficult,” he said.

Wow…

Wow

This is one of the most far-reaching statements made by a European leader about Europe since the Second World War.

It says that European Solidarity has Limits. And that no EU member state can expect to run up unmanageable debts and then call on the spirit of solidarity to get others to reach deep in their pockets, the more so if the sheer extent of the losses/debts might put even the strongest member states at risk.

President Wulff helpfully reminds us of the moral dimension of money, something usually overlooked.

What is money, after all, but an expression of moral value, above all an expression of confidence about trust and integrity? Not merely now, but based on hard-won reputation for reliability in preceding generations, and echoing down the decades still to come

Who wants to be paid in North Korean or Zimbabwean or Cuban currency? No-one.

Why? Because that currency is an expression of cruelty, inefficiency, waste and stupidity. It is literally worthless for most practical purposes.

Regular readers of this site know all about the moral dimension of money:

"So you think that money is the root of all evil?" said Francisco d’Aconia. "Have you ever asked what is the root of money?

Money is a tool of exchange, which can’t exist unless there are goods produced and men able to produce them.

Money is the material shape of the principle that men who wish to deal with one another must deal by trade and give value for value.

Money is not the tool of the moochers, who claim your product by tears, or of the looters, who take it from you by force. Money is made possible only by the men who produce. Is this what you consider evil?

When you accept money in payment for your effort, you do so only on the conviction that you will exchange it for the product of the effort of others. It is not the moochers or the looters who give value to money.

Not an ocean of tears nor all the guns in the world can transform those pieces of paper in your wallet into the bread you will need to survive tomorrow.

Those pieces of paper, which should have been gold, are a token of honor — your claim upon the energy of the men who produce.

Your wallet is your statement of hope that somewhere in the world around you there are men who will not default on that moral principle which is the root of money.

Thus the urgent moral and political question for the ailing Eurozone and its feckless members:

You expect (or at least hope) that whenever you toot the European solidarity trumpet a benign and benevolent Germany will do whatever it takes to prop you up, even if you have completely failed to run your affairs sensibly.

You expect Germany to be your keeper.

Have you asked Germany recently what it thinks about that? 

Oh, and by the way – who is Germany‘s keeper?
