<passage>:
A letter from an ill-mannered former high-school classmate of long ago, one of several like it, which I pass on in paraphrase: "I saw that your father had died," she wrote. "He was always so clever about money. Did he leave you a big estate? Did he figure out a way around the estate tax?" It's a rude question, but it has an answer. My sister and I have been going through my father's estate lately with his lawyer, and we're pawing through old, dusty files to find bank account numbers and rules for annuities, so maybe it's a good time to think about what my father, Herbert Stein, left to us. He did indeed leave some money. By the standards we read about in the Wall Street Journal or Sports Illustrated , it was not worthy of much ink. In any event, because of the class-warfare-based death tax, the amount that will be left is vastly less than what he had saved. As an economist, my father was famous for defending taxes as a necessary evil. But even he was staggered, not long before his death, when he considered the taxes on his savings that would go to the Internal Revenue Service. There are a few material, tangible items that an assessor will have to come in to appraise. There are my father's books, from his days at Williams College and the University of Chicago, many of them still neatly underlined and annotated in his handwriting, which did not change from 1931 until days before his death. Most of them are about economics, but some are poetry. "Loyalty." There is no item for it in the inventory of estate assets to be taxed. My father lived his life, especially in the latter years of it, in a haze of appreciation. Whatever small faults he could and did find with America, he endlessly reminded anyone who listened that the best achievement of mankind was America, whose current failings were trivial by historic standards, which was in a constant process of amelioration, and which offered its citizens the best chance in history for a good life. When he did consider the failures of American life in the past, especially institutionalized racism, he did so to note the astonishing progress that had been made in his lifetime. He had no use for those who held up a mirror of fault-finding from the left or the right when he could see in his own era what vast improvements in freedom had been made for blacks, Jews, women, Asians, Hispanics, and every other minority. and the thoughts of Alan Greenspan or the head of Goldman, Sachs My father's stance against seeking money for its own sake--so wildly unsuited to today's age, but so reassuring to his children--cannot be taken by the Treasury. Pop had a way of putting what I thought of as catastrophes into their rightful context. If I was hysterical about losing some scriptwriting job, my father would brush it aside as a basic risk, part of the life I had chosen. If my stocks went down, even dramatically, my father would explain that if I had a roof over my head and enough to eat, I was far, far ahead of the game. Most reassuring, my father would tell me that my family and I could always come to Washington, D.C., and live quietly, keeping him company, for which not a lot of money was required. (My father lived on a fraction of the income from his savings, even allowing for paying for his grandchildren's education.) Once, about 25 years ago, when my boss treated me unfairly, my father said that if it happened again, I should quit and he would take care of me until I found a job. I never needed to do it, but the offer hung in my mind as a last refuge forever. This reassurance--that somehow things will be all right, that there is a lot of ruin in a man, as well as in a nation, to paraphrase his idol, Adam Smith--has become part of me, and I can still summon it up when I am terrified because of a huge quarterly tax payment due or a bad day on the market. Again, the IRS taxes it at zero. My father himself, as far as I know, inherited no money at all from his father. He did inherit a belief that hard work would solve most problems, that spending beyond one's means was a recipe for disaster, that flashy showoff behavior with borrowed money was understandable but foolish. He did inherit enough common sense to tell his son that buying property he would never live in was probably a bad mistake. (He rarely spoke in moral absolutes. He believed instead that humans could and would make individual choices but that there were surely consequences to those choices that could be considered.) He passed these beliefs on to me, although they have become somewhat attenuated by my 20-plus years in the fleshpots of Hollywood. Still, I am one of the only men I know here who has never been drastically short of money (so far), and that I attribute to hearing his rules of prudence. Most of all, my father believed in loving and appreciating those persons close to him. He stayed close to all his pals from the Nixon days (and would not hear personal criticism of Pat Buchanan, who had been a friend and colleague, although he was bewildered by Pat's stands on many issues). He basked in the pleasure of the company of his colleagues and friends at the American Enterprise Institute, which he thought of as one of his three homes--the Cosmos Club and his extremely modest but well-situated apartment at the Watergate were the others. He could form attachments readily. Even in his last days in the hospital, he took a liking to a Ukrainian-born doctor and used to refer to him as "Suvorov," after the Russian general written of glowingly in War and Peace-- which still sits on the table next to his reading chair, with his notes on little pieces of paper in it. Even in his hospital bed, hearing my son's voice on the phone could make him smile through the fear and the pain. ("He sounds so sweet when he calls me 'Grandpa,' " my father said, beaming even with tubes in him.) Never once did my sister or I ever ask him for help that he hesitated, let alone declined, to give. Usually this was some research we were too lazy to do, but which he did without any resistance at all. When I was a child and had a chore like leaf raking that I didn't want to do, his simple answer was to say, "Let's do it together. It'll take half as long." I use that with my son almost every day, along with the devotion, and my father's example about his friends from long ago to make my life work. He stayed close with friends from Williams College Class of '35, especially Richard Helms of the CIA. He had lunch with one of his pals from Williams, Johnny Davis, class of '33, who got him a job as a dishwasher at Sigma Chi, days before he went into the hospital. This quality of devotion and the rewards I get from it are worth far more than any stocks or bonds in my father's estate--and cannot be taken away at the marginal rate of 55 percent. Plus, I can pass it on to my son without any generation-skipping surcharge. And he left something else of perhaps even greater value: a good name. Many people quarreled with my father's ideas about taxes or about when to balance the budget. He faced frequent opposition to his belief in a large defense budget. Of course, most of the people he knew disagreed with him about RN. But no one ever questioned that he came by his views honestly, by means of research and analysis and sometimes sentiment, but not for any venal reason or by the process of money changing hands. His reputation for honesty was simply without a speck of question upon it. This good name cannot be taxed at all, at least not right now. My sister and I and our children will have it for as long as we keep it clean. It's priceless, incalculable in value.
