Warren Buffett emails Microsoft exec (1997)

Buffett didn't seem to mind suffering an opportunity loss. He would write it up in a "gee, I was stupid" mailout and move on.

A lot of people seem to believe an opportunity loss is equivalent to a real world loss, and can justify legal action, retribution, all kinds of bad. I've never understood this, and it makes me happy because Buffett and I could not be futher apart politically and philosophically in other ways (unless I am mistaken he wasn't an overt fan of the welfare state. I'd be delighted if he included that in a model of public finance utility function stuff)
