<passage>:
My Father's Estate 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. They never had live-in help. My father washed the dishes after my mother made the meatloaf. My father took the bus whenever he could. His only large expenditure in his and my mom's whole lives was to pay for schools for his children and grandchildren. He never bought bottled, imported water he said whatever came out of the tap was good enough for him. They still used bargain-basement furniture from before the war for their bedroom furniture and their couch. I never once knew them to order the most expensive thing in a restaurant, and they always took the leftovers home. 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. But these are the trivia of what he left me and my sister. The really valuable estate cannot be touched by the death tax. The man's legacy to his family has almost nothing to do with anything that can be appraised in dollars and cents. The example of loyalty and principle: When he had just taken over as the chairman of President Nixon's Council of Economic Advisers, he hired a young staff economist named Ron Hoffman (brother of Dustin Hoffman). Almost immediately, John Dean, then White House counsel, came to see my father to tell him that he had to fire Hoffman. Apparently, Ron Hoffman had signed a public anti-war letter. The FBI, or whoever, said that showed he was not loyal and not qualified. My father said that this was a free country, that Ron Hoffman was hired as an economist not as a political flack for RN, and that he would not be fired because he disagreed with some aspect of Nixon policy. After much worrying, Hoffman was allowed to stay--and performed well. My father was loyal, and the IRS cannot impound that legacy. When RN ran into every kind of problem after June of 1972, most of which were unearned and a chunk of which was earned, my father never thought of disavowing him or even distancing himself from Nixon. Even though he had an appointment to the University of Virginia in his pocket, Pop several times extended his stay at the White House to help out with the struggles over inflation and recession, and never once publicly said a word against Nixon. Long after, when Nixon was blasted as an anti-Semite, my father told in print and in person of the Nixon he knew: kind "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 and valued them entirely on their merits to him, not on the basis of how much press or money the speaker had. He never once in my lifetime's recall said that any man or woman deserved special respect for riches--in fact, like Adam Smith, he believed that the pleadings of the rich merited special suspicion. He did not believe that my sister or I should devote our lives to the pursuit of money, and by his life set an example to us of pursuing only what was interesting and challenging, not what paid the most. I never knew him to chase a deal or a job (he never in his whole life applied for a job!) for any other reason except that it was of interest to him. He derived more pleasure from speaking to his pals at the book club of the Cosmos Club about John Keats than he did from giving speeches to trade associations that paid him handsomely. 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.
