First, reduce labor costs. One way to lower wages is to get salaried people to work as many hours for their check as you can convince them to do. This is one place where sociopaths shine.
Second, the ideal labor cost is $0, aka the ideal state of capitalism. When humans are involved, this means slavery. "Ideal" means the same as above: reduce labor costs wherever possible.
Convincing people to overwork is a sales job, and bending everybody around you to your preferred activities is practice for when you're going for funding or acquisition. Is there any MBA who wants to help build a company that doesn't get acquired? Gonna need those persuasion skills.
Working 80hrs a week? Congratulations, you've cut your own salary in half.
