“Is there a V.I.P. entrance? We are V.I.P.” That remark, by a donor waiting to get in to one of Mitt Romney’s recent fund-raisers in the Hamptons, pretty much sums up the attitude of America’s wealthy elite. Mr. Romney’s base — never mind the top 1 percent, we’re talking about the top 0.01 percent or higher — is composed of very self-important people.

Specifically, these are people who believe that they are, as another Romney donor put it, “the engine of the economy”; they should be cherished, and the taxes they pay, which are already at an 80-year low, should be cut even further. Unfortunately, said yet another donor, the “common person” — for example, the “nails ladies” — just doesn’t get it.

O.K., it’s easy to mock these people, but the joke’s really on us. For the “we are V.I.P.” crowd has fully captured the modern Republican Party, to such an extent that leading Republicans consider Mr. Romney’s apparent use of multimillion-dollar offshore accounts to dodge federal taxes not just acceptable but praiseworthy: “It’s really American to avoid paying taxes, legally,” declared Senator Lindsey Graham, Republican of South Carolina. And there is, of course, a good chance that Republicans will control both Congress and the White House next year.

If that happens, we’ll see a sharp turn toward economic policies based on the proposition that we need to be especially solicitous toward the superrich — I’m sorry, I mean the “job creators.” So it’s important to understand why that’s wrong.
