You just aren’t thinking like a billionaire, man. What you do is get the two people anyway, and still force the 70 hour work week.

Your job is not to find a reasonable steady state of operation. Your job is to exploit the resources before you (even the ones with emotions and families) to extract value for the shareholders in the most efficient way possible, before somebody even more evil and clever than you figures out a better way and we direct future fresh meat to his meat grinder instead of yours.
