Yes, salaries whatever. Who gives a shit about salaries when there are stocks available for employees. Employees get dividends from those stocks.
If there was $17B in revenue, and just $1B of that went through dividends, that means $500M is going to the employees. Because Gabe owns half, because he founded the company. Depending on how many shares someone has, which is most likely tied to how long you've been at the company, you rake in money. I know, cause I worked for a large corporation that did that same thing. My buddy who's still there is pulling $30k/year alone on that. Granted, that company has a much lower revenue:employee ratio. Valve is at the top of this category. So yeah, people who invest time and work into Valve make bank. As they should.
