Acknowledging what you don't know is the dawning of wisdom.

All the equity investors, in total, will surely bear a performance disadvantage per annum equal to the total croupiers' costs they have jointly elected to bear. This is an inescapable fact of life.

But there's so much good and so much strength left that I would not expect this country to suddenly founder.

Those of us who have been very fortunate have a duty to give back. Whether one gives a lot as one goes along as I do or a little and then a lot [when one dies] as Warrendoes is a matter of personal preference. I would hate to have people ask me for money all day long.
