The ethical rule is from Samuel Johnson who believed that maintenance of easily removable ignorance by a responsible office holder was treacherous malfeasance in meeting moral obligation. The prudential rule is that underlying the old Warner & Swasey advertisement for machine tools: "The man who needs a new machine tool, and hasn't bought it, is already paying for it". The Warner & Swasey rule also applies, I believe, to thinking tools. If you don't have the right thinking tools, you, and the people you seek to help, are already suffering from your easily removable ignorance.
Charlie MungerI've heard that one-half of the students at elite schools want to go into private equity or hedge funds. They want to keep up with their age cohorts at Goldman. This can't possibly end well in terms of meeting these expectations.
Charlie MungerI bet Richard Fuld doesn't have an ounce of contrition. It's just megalomania. When it's like that, you need rules to prevent catastrophe. When banks are borrowing the government's credit rating, you need rules to prevent stupid things.
Charlie MungerAccounting is a big subject and there are huge forces in play. The entire momentum of existing thinking and existing custom is in a direction that allows terrible follies to happen, and the terrible follies have terrible consequences.
