Peons when they earn enough money and have enough Food etc. will be able to buy furniture, this is how they will eventually be able to grow and have less chance of starving.
As Furniture gives Peons extra Energy which in turn makes them go to Work much more than without.
Basically Peons will go through a progression where they start the Game basically fearing that they will starve, to later on where they have more money and energy than they know what to do with.
Eventually i'd like to allow Peons to upgrade their Houses and maybe even create a Town System where the Peon's performance affects the Town's economy etc.
