The view of greed changed markedly in the 1980s, until then greed was seen as a vice. Thomas Aquinas described greed as a sin against God. And indeed greed is very close to covetousness, and there is a Commandment against that. But in the 1980s, Ivan Boesky, and of course Gordon Gekko (I know he wasn't real, but he was a caricature of a very real type), and Harry Enfield's loadsamoney (which was again a caricature of a real attitude) made greed respectable. So although it was not Thatcher alone, it was the Anglo-Saxon world of the Reagan-Thatcher years, and the attitudes that this engendered, which made respectable something which had been regarded, correctly in my view, as a serious vice.
