Corzine’s Downfall

The collapse this week of the broker-dealer MF Global and the due punishment of its chief executive Jon Corzine, who resigned Friday, have been and will be put to many political and rhetorical purposes. MF Global’s bankruptcy has been called, possibly, the first domino in a potential collapse of the European banking system; in this rendering, it’s a rough analog to the failure, in the spring of 2008, of Bear Srearns, which warned the chaos of autumn. It might well be cast as a stimulus for more government regulation, or smarter regulation; to some, it might even be a case study in overregulation. Every rationale for regulation seems to contain, as yang to its yin, an argument that regulation is actually to blame.
Corzine’s downfall is an update on Icarus, all illustration of arrogance. It reminds us that leverage kills, that it is dangerous to pick up nickels in front of a steamroller, that risk is risky, that pigs get fat while hogs get slaughtered. It complicates the Democrats’ hopes of controlling anti-Wall Street fervor in the Presidential election, because Corzine has been one of Barack Obama’s most generous supporters-a possible future Treasury Secretary. The Republicans will not soon let this one go.
It certainly further stains the reputation of Goldman Sachs. Corzine, a former C.E.O. of Goldman, took over a company partially owned by the firm of another ex-Goldmanite, Christopher Flowers, and managed, in a year and a half, to destroy it, in part while resisting oversight from a government regulator. That regulator comes from the Commodity Futures Trading Commission, whose chairman, Gary Gensle, is also a Goldman alumnus.
It further damages the perception, or myth, that a becoming-a-partner at Goldman Sachs indicates brilliance, or insures success or a lifetime inclusion in the vampire-squid-piracy, although you can find whisperings of a conspiracy theory that Goldman planted Corzine at MF Global in order to destroy it—a notion that is almost as deceiving as it is ridiculous.
Corzane’s collapse is also an occasion for taking-pleasure-in-others’-suffering. It is an occasion for those among Occupy Wall Street’s 99 per cent, who’d be ready to pitchfork him to pieces. It is also an occasion for the tiny cowering minority, who may resent Goldman for its perceived arrogance or cunning, or who may question the conceited folly and civic harm of Corzine’s spending over a hundred million of his own money to get elected to public office. The sentiment, among his peers, was that Corzine wasn’t so great a trader to begin with. And the sentiment was also that in the years since he had left Goldman, his skills, such as they were, had got rusty or outdated.
It is ironic that Corzine blundered by, and is being criticized for, among other things, betting too unbalancedly on Europe. That is, MF Global was banking on the hope that Portugal, Ireland, Italy, and Greece (whose bonds are collectively known as PIIGS) would not default on their debts by the end of the year. It might have turned out to be a good bet, were it not for the fact that it was made sneakily with money that was borrowed and perhaps even effectively stolen-or for the fact that he basically bet the firm, and the farm. Goldman Sachs, meanwhile, has been criticized, since the housing meltdown of 2008, for having profited from bets against the housing market—for shorting crappy derivatives based on mortgages. That was a good bet, except that Goldman made it while dumping those crappy derivatives on its unwitting clients.

The mocking and sneering on Corzine’s failure might come from ______.
A. protestants and rivals B. clients and employers
C. experts and officials D. PIIGS and regulators

材料一：孔家店在五四运动时期曾被砸烂，孔老二在“ * * ”期间曾被批倒批臭过。但在我们的潜意识里，以儒家为代表的传统文化却一直生生不息，像是变成了我们的血液，在我们的全身奔涌流淌……材料二：韩国人十分重视长幼尊卑，家长在家里仍然是绝对的权威。一些韩国人每年二月和八月初一，都要按照从中国传过去的传统方式到文庙祭祀孔子。人们头戴儒冠，身穿黑色古代祭服，毕恭毕敬地向孔孟行礼。中国封建时代的县学和书院，现在都已荡然无存，而韩国还完整地保存着281所乡校和84所书院。他们在这里设立“忠孝教育馆”，开展有关儒学的学术活动。至今，韩国的社会共同道德仍然是中国宋代时期提出的“八德”：“孝弟、忠信、礼义、廉耻。”中国的《朱子家礼》在元代时传入朝鲜，现在仍然是韩国人家庭伦理的规范基础。结合材料，说明我们应该如何对待传统文化。
