I believe their mindset to be as shareholder-oriented as can be found in the universe of large publicly-owned companies.
This statement is more interesting than it first appears, in two ways:
First, Buffett is notoriously stingy at giving Berkshire executives stock or stock options. So many of his managers have little or no stock in the company, which makes it hard to claim they are shareholder-oriented (as opposed to oriented to whatever other incentive goals Buffett sets for them).
Second, many investors routinely complain that a big problem with large, publicly-owned companies is that their managers typically own very little stock and are therefore out of alignment with shareholders.
Once again, as with the S&P 500 index, Buffett perhaps chooses an overly easy bar to jump over.
