> If you have a hand of cards you want to optimize it makes sense to keep discarding and redrawing your worst cards.

But this makes sense _in a game with a fixed hand size_. But a company's staff should grow over time. So shouldn't one have an ROI-based criteria where you want each team member to help grow generate meaningfully more revenue than they cost to employ. If my "lowest" performing team members still make meaningfully more money than they cost to employ, they still increase my ability to hire more.
