Whilst it is technically a salary, since the business is wholly owned by her and her family it is effectively a dividend, so it isn't quite accurate to compare it to CEO's of non-wholly owned private or public companies. Other CEO's might have gotten paid more since they might own enough stocks in the company to receive dividends, or share awards etc...
That's a fair point, it would be more interesting to compare the salary to equivalent, family-owned private companies (although I'm sure most of them don't disclose that sort of thing).
