Thank you! Yes, I agree that's a pretty glaring flaw. I ran out of time for doing nice mouse over text explaining what hiring the worker would provide (for example, I think at submission time the stone tool maker "knapper" consumed 1 food and 1 stone to produce 0.1 stone tools each second). I'm working on that to add by the end of the month along with some other polish and added features.
The narration was not in the original plan; I added i ton a whim when playtesting. I'm glad you liked it :)
