yes, without dissecting this 10 ways to Sunday , WEB would have likely preferred not to have the B's, but was forced to jump onboard having 2 share classes - when some people were trying to flog a security/fund/LP etc, made up of just BRK sliced into smaller pieces. Then he split the B's to accommodate the small BNSF shareholders. I'd maintain $1000 is a small "price" to pay for entry into a diversified well run....we expect going forward, business. That's just one iPhone that lots of people carry around.
but i'm probably wrong.
