George Orwell once blamed the demise of the English language on politics. It's quite possible he never read a prospectus.
Do not imagine that you can escape judgment if you rob people with a false prospectus rather than with a knife.
It's a great myth that the British public want our soldiers to be sent into harm's way on a bogus prospectus for ignoble reasons. There is nothing patriotic about that. It is the opposite of patriotism.
Any time anybody offers you anything with a big commission and a 200-page prospectus, don't buy it. Occasionally, you'll be wrong if you adopt "Munger's Rule". However, over a lifetime, you'll be a long way ahead-and you will miss a lot of unhappy experiences.
