Christmastime is bonus time on Wall Street, and the Gucci set has been blessed with another record harvest.

Forget the turbulence in the financial markets and the subprime debacle. Forget the dark clouds of a possible recession. Bloomberg News tells us that the top securities firms are handing out nearly $38 billion in seasonal bonuses, the highest total ever.

But there’s a reason to temper the celebration, if only out of respect for an old friend who’s not doing too well. Even as the Wall Streeters are high-fiving and ordering up record shipments of Champagne and caviar, the American dream is on life-support.

I had a conversation the other day with Andrew Stern, president of the Service Employees International Union. He mentioned a poll of working families that had shown that their belief in that mythical dream that has sustained so many generations for so long is fading faster than sunlight on a December afternoon.
