im not sure how much you know about businesses, but their number 1 goal is to make money...
lets assume that the average salary including is 20,000.
20,000 * 400 = $8 Million
i dont give a fuck how big your company is. you notice $8mil, and if you can get the same effect for $2 mil. by not giving all of them a flat out salary, youre sure as hell going to do that
think about it this way.... that would be $6mil more that they can put into their f1 teams which make them a hell of a lot more money than skiing ever will
