I know salaries in six figures get people all wound up. But I was VP of HR (including compensation) for a company in the Fortune 10, and these numbers are not at all excessive. For a CEO to make < 1% of gross is quite reasonable.
BTW, one important reason why the expense numbers don't add up is the costs of putting on the races -- a number not shown. On the national level, you have the entire traveling circus that needs to do 20+ races a year around the country. Just the fuel bill alone must be impressive, let alone the travel expenses for the crew. But then there are seven divisions, each with a staff, and equipment, and travel costs for dozens of races.
Back to compensation. Even as a total, many, many companies have salaries and benefits that represent 50, 60, even 70+% of gross. Yes, it varies by industry, but the numbers here, under 20% don't point to a huge problem with salaries.
You can argue all you want about whether the individuals earn their salaries, and I'll not get involved in that discussion. But from a raw numbers perspective, there are no red flags compared to many companies and non-profits.
