Actually the Class B shares DID, in fact, help the Class A shareholders, since Class A shares could be converted to 30 Class B Shares. The reverse wasn't true....class B shares could not be converted to class A shares. At the time of their creation, I believe that the Class B shares were around $1200/share which would make the Class A about $36,000 at the time. At $1200/share it allowed me to gift my kids each with 8 shares of BRKb and still stay under the $10,000 gift exclusion limit. I merely converted 1 share. Also, the investment trusts were specifically created to allow one to overcome that original issue. By owning shares or units in the investment trust, you got a small piece of BRKa without having to put down $36,000 for a single share. Buffett didn't think that was good for Berkshire and so he created the B-shares in response which killed the investment trust concept.
