American social arrangements, economic arrangements, the degree of inequality in American life, the relatively small role played by the government in American public life and so forth, compares to exactly the opposite conditions in most of the European societies.

The different American experience of the 20th Century is crucial because the lesson of the century for Europe, which essentially is that the human condition is tragic, led it to have a build a welfare system and a set of laws and social arrangements that are more prophylactic than idealistic. It's not about building perfect futures; it's about preventing terrible pasts. I think that is something that Europeans in the second half of the 20th century knew in their bones and Americans never did, and it's one of the big differences between the two Western cultures.

There is nothing to be said for being crippled. You don't see the world better or clearer, nor do you develop some special set of skills by way of compensation.

We have responsibilities for others, not just across space but across time. We have responsibilities to people who came before us. They left us a world of institutions, ideas or possibilities for which we, in turn, owe them something. One of the things we owe them is not to squander them.

Contrast 1968, when the CEO of General Motors took home, in pay and benefits, about sixty-six times the amount paid to a typical GM worker. Today the CEO of Wal-Mart earns nine hundred times the wages of his average employee. Indeed, the wealth of the Wal-Mart founder's family in 2005 was estimated at about the same ($90 billion) as that of the bottom 40% of the US population: 120 million people.

We need to start talking about inequality again; we need to start talking about the inequities and unfairnesses and the injustices of an excessively divided society, divided by wealth, by opportunity, by outcome, by assets and so forth.

Reality is a powerful solvent.
