Look at the history of national debt: Great Britain, Germany, and France were all once in the situation of today’s Greece, and in fact had been far more indebted. The first lesson that we can take from the history of government debt is that we are not facing a brand new problem….

After large crises that created huge debt loads, at some point people need to look toward the future. We cannot demand that new generations must pay for decades for the mistakes of their parents. The Greeks have, without a doubt, made big mistakes. Until 2009, the government in Athens forged its books. But despite this, the younger generation of Greeks carries no more responsibility for the mistakes of its elders than the younger generation of Germans did in the 1950s and 1960s. We need to look ahead. Europe was founded on debt forgiveness and investment in the future. Not on the idea of endless penance. We need to remember this.
