For years I have read the morning paper and harrumphed. There's a lot to harrumph about now.

The quality of the medical care delivered, including the pharmaceutical industry, has improved a lot. I don't think it's crazy for a rich country like the USto spend 15% of GDP on healthcare, and if it rose to 16-17%, it's not a big worry.

The possibility that stock value in aggregate can become irrationally high is contrary to the hard-form "efficient market" theory that many of you once learned as gospel from your mistaken professors of yore. Your mistaken professors were too much influenced by "rational man" models of human behavior from economics and too little by "foolish man" models from psychology and real-world experience.

The secret to happiness is to lower your expectations. ...that is what you compare your experience with. If your expectations and standards are very high and only allow yourself to be happy when things are exquisite, you'll never be happy and grateful. There will always be some flaw. But compare your experience with lower expectations, especially something not as good, and you'll find much in your experience of the world to love, cherish and enjoy, every single moment.

Berkshire was built on the eternal verities: basic mathematics, basic horse sense, basic fear, and basic diagnosis of human nature to make predictions regarding human behavior. We stuck to the basics with a certain amount of discipline and it has worked out quite well.
