What about international competition? We now think of America as a nation doomed to perpetual trade deficits, but it was not always thus. From the 1950s through the 1970s, we generally had more or less balanced trade, exporting about as much as we imported. The big trade deficits only started in the Reagan years, that is, during the era of runaway finance.

And what about that trickle-down? It never took place. There have been significant productivity gains these past three decades, although not on the scale that Wall Street’s self-serving legend would have you believe. However, only a small part of those gains got passed on to American workers.

So, no, financial wheeling and dealing did not do wonders for the American economy, and there are real questions about why, exactly, the wheeler-dealers have made so much money while generating such dubious results.

Those are, however, questions that the wheeler-dealers don’t want asked — and not, I think, just because they want to defend their tax breaks and other privileges. It’s also an ego thing. Vast wealth isn’t enough; they want deference, too, and they’re doing their best to buy it. It has been amazing to read about erstwhile Democrats on Wall Street going all in for Mitt Romney, not because they believe that he has good policy ideas, but because they’re taking President Obama’s very mild criticism of financial excesses as a personal insult.

And it has been especially sad to see some Democratic politicians with ties to Wall Street, like Newark’s mayor, Cory Booker, dutifully rise to the defense of their friends’ surprisingly fragile egos.

As I said at the beginning, in a way Wall Street’s self-centered, self-absorbed behavior has been kind of funny. But while this behavior may be funny, it is also deeply immoral.

Think about where we are right now, in the fifth year of a slump brought on by irresponsible bankers. The bankers themselves have been bailed out, but the rest of the nation continues to suffer terribly, with long-term unemployment still at levels not seen since the Great Depression, with a whole cohort of young Americans graduating into an abysmal job market.

And in the midst of this national nightmare, all too many members of the economic elite seem mainly concerned with the way the president apparently hurt their feelings. That isn’t funny. It’s shameful.
